Abstract:
Abstract Pink and post-bloom sprays of 2 insecticides were evaluated for efficacy in controlling the 1st generation of ABLM in a 15-year-old semi-dwarf apple orchard rat Hamden, CT. Single-tree plots were arranged in a completely randomized design with 5 replicates/treatment. Insecticides were applied to runoff ; on 23 Apr (pink) and 20 May (10 days after bloom) with a Solo knapsack sprayer operated at 15 psi. Effectiveness of each treatment was determined |ion 13 Jun by randomly collecting 10 leaf clusters/replicate at a height of 1.5 m and counting no. of tentiform mines.

Abstract:
Abstract This experiment was conducted at 4 locations (lawns) in Clarke, Covington, Jasper and Newton Counties in south Mississippi. Each location consisted of 3 replications 1000 ft2 each. Treatments were made on 20 Jul in Covington and Jasper Counties and on 26 and 28 Jul in Clarke and Newton Counties, respectively. Granular formulations were applied with a ferti-lome hand-pushed spreader. Liquids were applied with a Hudson knapsack sprayer using a hollow-cone nozzle at 30 psi, and a spray volume of 2 gal/1000 ft2. Imported fire and hill density was determined by visual observation. Pretreatment counts were made on 21 Jul and post-treatment counts were made on 22 Aug.

Abstract:
Abstract The experiment was conducted in a golf course fairway in Moraga, California. Experimental design was a RCB with four replications. Plot size was 5 x 20 ft granular formulations were shaken from a glass jar manually over the plots. Liquids were applied with a Solo® knapsack sprayer using a hollow cone nozzle at 32 psi, and a 6 gal/1,000 ft2 spray rate. Immediately after application, treatments were watered-in with 1 inch of water. Pretreatment grub density was determined on 23 Sep by cutting 51ftxlftx3in randomly selected sections in the sod in each plot and counting the number of grubs. Insecticide treatments were applied at the same date. Postreatment grub density was determined in the same manner on 6 Oct.

Abstract:
Abstract The experiment was conducted in a golf course fairway in Apple Valley, Calif. Experimental design was a randomized complete block with 4 replications. Plot size was 5 × 20 sq ft. Granular formulations were shaken from a glass jar manually over the plots. Liquids were applied with a Solo knapsack sprayer using a hollow-cone nozzle at 32 psi, and a spray rate of 6 gal/1000 sq ft. Immediately after application, treatments were watered in with 0.5 inch of water. Pretreatment grub density was determined on 15 Sep by cutting 41 ft × 1 ft × 3 inch randomly selected sections in the sod in each plot and counting the number of grubs. Insecticide treatments were applied the same date. Posttreatment grub density was determined in the same manner on 14 Oct. Average thatch thickness was 0.5 inch. Water was pH 7.4. The course was irrigated daily with 0.25 inch as normal.

Abstract:
Abstract Season long control of SCB was tested in a small plot experiment located at the St. Gabriel Research Station, St. Gabriel, LA. Thirteen insecticide treatments were evaluated in a field of first ratoon sugarcane. The experimental design used a RCB with 5 replications and each plot consisting of 3 rows (1.8 m centers), 7.3 m in length equivalent to 0.004 hectares per plot. Insecticides were applied when SCB infestations exceeded the economic threshold level of 5% of the stalks containing live larvae in the leaf sheaths. The spray treatments were applied to the sugarcane canopy of all rows in each plot with a knapsack sprayer (pressure and output ca. 1.41 kg/cm2 and 250 liters/ha, respectively). The 2 granular treatments were applied using a 400 ml shaker jar calibrated to deliver the designated amount to the canopy (Aug 5, Sep 3, and Sep 23). SCB damage was assessed by counting the number of bored internodes, exit holes, and total internodes from 100 randomly-selected stalks (5 replications, 20 stalks/rep) of sugarcane in each treatment (Nov 6).

Abstract:
Abstract This experiment was conducted on 2 golf course fairways with sandy loam soils in Jackson and Hancock Counties on the Gulf Coast of Mississippi. Experimental design was a randomized complete block with 6 replications 1000 ft2 each. Treatments were made on 27 Jun in Jackson County and on 28 Jun in Hancock County. Granular formulations were applied with a ferti-lome hand-pushed spreader. Liquids were applied with a Hudson knapsack sprayer using a hollow-cone nozzle at 30 psi, and a spray volume of 3 gal/ 1000 ft2. Immediately after application, treatments were watered in with 0.3 inch of water. Mole cricket density was determined by applying 2 gal of soapy water (2 fl oz liquid soap/gal water) to 4 ft2 of turf/plot. Pretreatment counts were made on 27 Jun and post-treatment counts were made on 13 Jul.
