Abstract:

In a small plot field test, imidacloprid (Provado®), oxydemeton- methyl (Metasystox-R®), RH -7988 (Aphisttar®, Rohm and Haas), pirimicarb (Pirimor®), methamidaphos (Monitor®), and endosulfan were effective in significantly reducing the number of aphids in broccoli within 4 days of treatment (DAT). At 14 DAT, Provado, Metasystox-R, and Monitor continued to exhibit a significant reduction of aphids relative to the untreated check Pymetrozine (CGA- 215944, Novartis) at 0.022 lb AI/A did not effectively reduce aphids in this test.

Abstract:

This thesis focuses on diffusion channel design for broccoli storage, an important cash crop and consumer commodity in Canada. Experiments were first conducted to determine the respiration rate of broccoli in modified atmosphere conditions created by the produce metabolic activity inside closed chambers, at four different temperatures in the cold room of 3, 7, 13, and 24$ sp circ$C. The respiration rate decreased with a reduction of O$ sb2$ concentration inside the chamber. A model to predict the respiration rate of broccoli as a function of O$ sb2$ concentration at different temperatures was developed. Experiments were then carried out to determine the cross sectional area and length of diffusion channel leading to various final O$ sb2$ (steady-state) concentrations during the storage of broccoli. Combinations of cross sectional area of 0.04, 0.18, and 1.15 cm$ sp2$ and length of 0.6, 3, 7, 12, 18, and 25 cm were tested. The carbon dioxide produced through respiratory process was absorbed by placing hydrated lime inside the chambers such that the two-component molecular diffusion model by Ratti et al. (1993) could be evaluated. The length and cross sectional area of diffusion channel have a significant effect on the final level of O$ sb2$ (steady-state) concentration. The Ratti model then served as a basis for a modified model for predicting the length of diffusion channel required to obtain a given O$ sb2$ concentration as a function of the mass of stored broccoli and the cross sectional area of the diffusion channel.

Abstract:

Several pyrethroid insecticides were evaluated and compared for efficacy against lepidopterous insect pests in broccoli. Zeta-cypermethrin (Mustang®) was compared at two rates, tralomethrin (Scout X-tra®) formulations were compared, lambda-cyhalothrin (Karate®), and esfenvalerate (Asana®) were evaluated for efficacy against cabbage looper (Trichoplusia ni. CL). Following each of the applications, most of the treatments reduced the number of larger sized CL relative to the untreated check. The two rates of Mustang performed similarly as did the two formulations of Scout X-tra, emulsifiable concentrate versus gel.

Abstract:

An exploratory field study provided results of postemergence herbicide weed control efficacy and broccoli tolerance. Pyridate (Tough®), clopyralid (Stinger®), and oxyfluorfen (Goal®) did not cause any crop stand reduction compared to bentazon (Basagran®) that completely reduced the broccoli stand. Tough and Goal at the lower rates tested caused marginally acceptable broccoli injury. Goal effectively controlled pigweed species (Amaranthus sp.), groundcherry (Physalis wrightii), and purslane (Portulacç oleracea). Tough gave good control of pigweed and purslane but not groundcherry. Stinger was safe on broccoli and marginally controlled groundcherry. In a second field study, Tough and Goal were evaluated for cheeseweed control. Goal marginally controlled cheeseweed at all rates tested and caused marginally acceptable injury at the two lowest rates. Tough was relatively safe at the lower rates but did not adequately control the cheeseweed.

Abstract:

Exploratory field studies conducted in broccoli showed that clomazone (Command®) and isoxaben (Gallery®) were extremely phytotoxic to broccoli when applied preemergence (PREE) on the soil surface after planting. Both offered good weed control of the weeds present. Napropamide (Devrinol®) caused moderate crop injury and marginally acceptable weed control.

Full text

Abstract:

An investigation was made of concepts for mechanizing the selective harvest of broccoli. Selective harvesting has advantages over once-over harvesting because of greater yield and reduced handling requirements. Results of a preliminary experiment measuring broccoli stalk cutting forces indicated that the blade speed for a broccoli cutting mechanism should be as fast as possible to minimize the required cutting force. A manually-directed, powered cutting device was designed to fit readily into existing broccoli harvest systems. In tests the first year with the device, the harvest rate was substantially faster than hand harvest rates measured at commercial farms, but the level of leaf-stripping achieved with the device was unacceptably low. A new cutting device included an added leaf-stripping mechanism and had a mounting arrangement that allowed the harvesting of two double rows at once. In tests the second year, leaf-stripping was much improved, but the overall harvest rate was only marginally better because of extra manipulation required to activate the leaf-stripping mechanism. Measurements related to mechanical harvesting were made on broccoli plants both years. Head height, stalk diameter, and head weight were strongly affected by harvest time and in-row plant spacing. Height and stalk diameter were moderately correlated to head diameter. A regression model for predicting head diameter from height and stalk diameter indicated that potential exists for using a combination of the two parameters for sizing broccoli heads. Head weight was highly correlated to height and stalk diameter. Two concepts for automatic mature head selection were evaluated. The results of an experiment measuring the force required to uproot broccoli plants indicated that physically sizing broccoli heads using spaced fingers would only be feasible if late season irrigations could be incorporated in a harvest system. Digital image processing for head selection appears more promising. An image processing algorithm based on the gray level run length method of textural analysis was developed for predicting broccoli head area. Accurate head classification was obtained with the model. For an automatic selective harvester, an image processing system can be coupled with a cutting device with the major advantage that leaf~stripping can be accomplished automatically during the harvesting action.

Abstract:

Nicosulfuron, quinclorac, triflusulfuron, MKH-3586, pyraflufen, and tribenuron applied PREE appeared to be safe on the lettuce crops while demonstrating variable activity against weeds. Head lettuce and romaine were not as tolerant to POST herbicides compared to PREE herbicides. Sulfosulfuron, MKH-3586, rimsulfuron, ethametsulfuron and pyraflufen applied POST caused various degrees of injury on the lettuces that were less injurious than other treatments. Thifensulfuron, nicosulfuron, and quinclorac applied PREE or POST showed acceptable broccoli tolerance. Ethametsulfuron exhibited adequate safety when applied POST on broccoli. Thifensulfuron, nicosulfuron, and quinclorac applied PREE also showed spinach tolerance. Similar to head lettuce and romaine spinach was not as tolerant to POST herbicides compared to PREE herbicides.

Abstract:

Downy mildew of broccoli, caused by the fungus Peronospora parasitica, is a perennial disease problem affecting winter broccoli production in Arizona. During 1985-87, potential systemic fungicides were evaluated in the field for disease control. In the 1985-86 season, a period of high disease incidence, lesion development was significantly reduced by fosetyl-Al (44 %), phosphorous acid (42 %), oxadixyl + mancozeb (35 %), chlorothalonil (33 %), metalaxyl + mancozeb (30 %) and metalaxyl + chlorothalonil (28 %). During the 1986 -87 growing season, disease incidence was low and lesion development was significantly reduced by phosphorous acid (82 %), fosetyl -Al or oxadixyl + chlorothalonil (77 %), metalaxyl + chlorothalonil (68 %) and chlorothalonil (54 %). Fosetyl-Al, phosphorous acid and oxadixyl were as effective as currently available fungicides ( metalaxyl and chlorothalonil) for control of downy mildew of broccoli in Arizona.

Abstract:

Downy mildew of broccoli, caused by the plant pathogenic fungus Peronospora parasítica, can be found every year in many broccoli fields in Arizona. The severity of the disease is affected by the occurrence and duration of weather conditions favorable for disease development. During the 1990-91 vegetable season in western Arizona, different fungicides and rates of materials were evaluated in the field for disease control. Ridomil /Bravo and Bravo, which are currently registered for use on broccoli to control downy mildew, and Aliette, which is currently not registered for use on this crop, provided significant disease control compared to untreated plants. Rovral and Topcop did not control downy mildew on broccoli.

Abstract:

Downy mildew of broccoli is caused by the plant pathogenic fungus Peronospora parasitica. Cool damp weather with high humidity is highly favorable for sporulation, dissemination of spores, and infection by this pathogen. The severity of disease is affected by the duration of weather conditions favorable for disease development. Potential new fungicides were evaluated for disease control in field trials conducted during 1994 and 1995. Downy mildew did not occur in the 1994 trial. In 1995, disease was moderate and all tested fungicides provided significant disease control compared to no treatment at all. Three new fungicides, Fluazinam, Dimethomorph, and ICIA-5504, show promise as potential new materials for control of downy mildew on broccoli.

Abstract:

Peronospora parasitica is the pathogen responsible for causing downy mildew of broccoli, cabbage and cauliflower. Cool moist environmental conditions favor the development of downy mildew on these crops. Several potential new fungicides were evaluated for control of this disease on broccoli in 1998. The final severity of downy mildew in this trial was moderately high. Significant reduction in disease severity compared to nontreated plants was achieved by application of standard compounds such as Aliette, Bravo, maneb and Trilogy as well as the new fungicides Actigard, an Unknown, Curzate, Quadris, RH-7281, BAS 490, Acrobat and BAS 500. Broccoli yield was significantly increased compared to nontreated plots by treatments with Bravo, Curzate, Acrobat, BAS 500, Quadris, maneb, Actigard, BAS 490, an Unknown, RH-7281 and Aliette. The future registration and subsequent availability of one or more of these new chemistries for broccoli and related crops could help minimize the risk of development of resistance to fungicides used to manage downy mildew.

Abstract:

Thesis (MTech (Food technology))--Cape Technikon, Cape Town,1998
To establish the optimum pasteurisation procedure, the effects of sous-vide heat processing on the pH, ascorbic acid and sensory aspects of broccoli (Brassica oleracea var. Italica) were studied. Broccoli florets were blanched using steam and ammonia(NH3)-steam, chilled to <2°C in ice water at O°C, and vacuum packaged. Sous-vide processing proceeded immediately at pasteurisation temperatures 73°, 76°, 79°, 82° and 85°C to a p~ = 100. Directly afterwards, the pH of the processed sous-vide broccoli was measured and percentage L-ascorbic acid loss calculated, by comparing sous-vide broccoli with unprocessed controls from the same broccoli head. Objective colour measurements were made using CIELAB L*, a* and b* co-ordinates. Consumer acceptance was tested using paired preference analysis. The same analyses were repeated after storage at 2° - 4°C for 21 days. Suitable statistical analyses showed significantly higher (P<0.05) pH-values in the case of NHrsteam-blanched broccoli, with the result that the ascorbic acid retention of NH3-steam broccoli was significantly lower (P<0.05) than that of steam blanched broccoli. Higher pasteurisation temperatures, and resulting shorter heat processing times, ii showed a significant reduction (PO.05) taste preference was detected for broccoli from either blanching method.

Abstract:

Downy mildew of broccoli, caused by the fungus peronowora parasitica, usually can be found on a yearly basis in broccoli fields in Arizona During the 1988-89 season, four different fungicides were evaluated in the field for disease control. All four materials significantly reduced the number of downy mildew lesions on treated broccoli leaves. Although significant disease control was achieved the average head weight was not significantly different when treated plants were compared with untreated plants. Light to moderate levels of downy mildew or late development of disease, as found in this trial, apparently do not require application of fungicides to prevent yield loss. Ridomil/Bravo and Bravo currently are registered for disease control, while SDS-59891 and Aliette are not registered for use on this crop.

The new insecticide Imidacloprid (NTN 33893), which is currently being developed for use on vegetable crops, was evaluated on broccoli for control of aphid species. Studies conducted in the spring of 1991 showed that this material applied postemergence as a granular formulation was extremely effective in preventing aphid colonization throughout the season. Aphid control and broccoli yields were significantly greater in plots treated with Imidacloprid. Due to low numbers of aphids in 1992, we were unable to detect differences in aphid numbers between Imidacloprid treatments and the untreated control.

Abstract:

Downy mildew of broccoli is caused by the plant pathogenic fungus Peronospora parasitica. Cool damp weather with high humidity is highly favorable for sporulation, dissemination of spores, and infection by this pathogen. The severity of disease is affected by the duration of weather conditions favorable for disease development. Potential new fungicides were evaluated for disease management in a field trial conducted in 1996. Disease pressure was moderate and all tested fungicides except Ridomil MZ 72 and one Ciba G + Mancozeb treatment significantly reduced the number of downy mildew lesions on leaves compared to plants not treated with a fungicide. The level of disease reduction provided by all chemical treatments was equivalent to that given by Aliette and Bravo, two fungicides currently available for control of downy mildew on broccoli.

Abstract:

Mestrado em Ciências Empresariais
Dada a importância que o planeamento e previsão acarretam, Um Plano de Negócios deve ser o primeiro momento na criação de um negócio (Delmar e Shane, 2003). Desta forma, o presente Trabalho Final de Mestrado pretende avaliar a viabilidade da criação de um restaurante de alimentação saudável ? Broccoli - no concelho de Lisboa. O restaurante apresenta características diferenciadoras e propõe ser a resposta à procura por soluções mais saudáveis no que à alimentação diz respeito, nomeadamente com regimes alimentares baixos em açúcar e com um vasto recurso a brócolos nas refeições. Para apurar a pertinência da criação de tal negócio em Lisboa, foram tidos em conta os fatores internos e externos, tanto do ambiente como da indústria, com apoio dos dados primários recolhidos e secundários disponíveis. A viabilidade financeira do negócio foi testada através da previsão de vários cenários, seja no volume de vendas, preços de venda ao público e valor da remuneração dos colaboradores. O projeto, com uma taxa de atualização de 8,66%, apresenta um VAL de 35 697 euros e uma TIR de 37,64%. Já o Pay Back Period é de 4 anos. O ponto crítico é atingido entre o primeiro e o segundo ano de funcionamento. A metodologia do Plano de Negócios assenta no trabalho desenvolvido por Kuratko (2009), pois a organização proposta parece ser a que melhor se adequa ao presente TFM; quer por apresentar um índice prático,como por ser aquele que aparenta ter mais em conta os fatores do ambiente externo.
Given the importance of planning and forecasting, a Business Plan should be the first step in setting up a business (Delmar and Shane, 2003). In this way, the present Final Master's Work intends to evaluate the feasibility of creating a healthy food restaurant - Broccoli - in the municipality of Lisbon. The restaurant has differentiating characteristics and proposes to be the answer to the search for healthier solutions in terms of food, namely with low sugar diets and a wide use of broccoli in meals. In order to determine the relevance of the creation of such a business in Lisbon, the internal and external factors of the environment and the industry were considered, with the support of the primary data collected and secondary data available. The financial viability of the business was tested by predicting various scenarios, whether in sales volume, retail sales prices or space rent. The project, which market premium discount rate is 8,66%, reveals a VAL of 35 697 euros and a TIR of 37,64%. The Pay Back Period is 4 years. The break-even point is reached between the first and the second year of operations. The methodology of the Business Plan is based on the work developed by Kuratko (2009), because the proposed organization seems to be the one that best fits this TFM; either because it presents a practical index, as it is the one that seems to take more into account factors of the external environment.

Abstract:

Carfentrazone at 0.0125 and 0.025 lb AI/A was safe on all three lettuce cultivars. No stand reduction was observed. Sulfentrazone confirmed the initial screening test rate range of 0.05 to 0.1 lb AI/A for demonstrating marginal lettuce safety. Flumetsulam and thifensulfuron showed greater selectivity only in head lettuce while severely injuring romaine and red leaf lettuce. Rimsulfuron caused considerable stand reduction of all three lettuce cultivars. Sulfentrazone, fluroxypyr, and thifensulfuron exhibited good tolerance on broccoli as no stunting or stand reduction was observed at maturity.

Abstract:

Three rates of Stinger (Clopyralid) were evaluated for weed control, crop safety and soil persistence in broccoli. Efficacy tests indicated that 0.25 pt./A was ineffective in controlling volunteer alfalfa; while 0.5 pt produced marginal control and 1.0 pt. produced excellent control. No injury was noted at any rate. 140 days after treatment, injury was moderate to severe to alfalfa, moderate to tomatoes, cotton, carrots and lettuce and slight to onions.
