Experimental plots were established in continuous corn field with a Waukegan silt loam soil at the Rosemount Agricultural Experiment Station.

Granular treatments were applied at planting ahead of the presswheel using modified Noble applicators. Aluminum barriers, each surrounding 4.6 cm of 2 rows and extending 10 cm below and 15 cm above the soil, were installed 8 Jun when corn was just emerging. Corn stand within the barriers averaged 40 plants. On 9 Jun between 6 and 7 p.m. each plot was infested with 60 BCW larvae (50% 4th, 50% 3rd instars). The next morning, between 7-9 a.m., all liquid rescue treatments were applied within the appropriate barrier arenas. Liquid insecticides were applied in 187 liters of water/ha while the nematodes (BioVector) were applied in 750 liters/ha. Wind speed ranged from 0 to 3 km/h, while soil temperatures hovered near 22°C. Plots were examined 3, 6, and 10 d after infestation, injured plants were marked and plant injury was recorded as leaf feeding. Statistical analyses were performed after determining the final fate of each plant.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73883614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test orchard was located at the Tree Fruit Research and Extension Center, Wenatchee. Test trees were 17-year-old non-spur ‘Red Delicious’. The orchard was irrigated by under-tree sprinklers on a 14-day schedule. The test design consisted of 4 single-tree replicates in randomized complete blocks. Treatments were applied with a handgun sprayer at 300 psi to the point of drip, simulating a dilute spray of approximately 400 gal/acre. In all cases the first treatment was applied at the beginning of the egg hatch, 28 May, 250 degree days following first capture of moths in a pheromone trap. The number of sprays applied for each CM generation depended on the chemical and rates used and are shown in the table. After the first CM generation (16 Jul), 100 fruit from each replicate were examined and the number damaged by CM recorded. At harvest (29 Aug), 200 fruit were picked from each replicate and examined for damage by CM and PLR. CM damage was rated as a “sting” (an unsuccessful entry in the fruit denoted by a scar but no penetration) or a deep entry. Mites were sampled in Jul, Aug and Sep. Twenty-five leaves were collected from each tree. In the laboratory leaves were processed through a mite brushing machine and each mite species was counted with aid of a dissecting microscope.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84635113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatments were arranged in a RCB design, replicated 4 times. Applications were made with a tractor mounted boom equipped with a compressed air system calibrated to deliver 56.2 liters total spray/ ha through Teejet X-8 hollow cone nozzles (2/row) at 2.39 kg/cm2. Insecticide treatments were applied on 10 and 16 Sep. Methyl parathion 4 EC (0.37 kg [AI]/ha) was applied on an “as needed” basis for boll weevil control. Efficacy was determined by examining 25 squares/plot for evidence of damage and the presence of larvae. High numbers of soybean looper larvae were observed in the plots during Sep and visual defoliation estimates were made to evaluate differences among treatments. Each plot was scored as follows: 0 (no feeding damage), 1 (feeding damage within the lower 1/3 of the plant), 2 (feeding damage to the lower and middle 1/3 of the plant) or 3 (feeding damage throughout the plant). No rainfall occurred during this test. Sprinkler irrigation was provided “as needed” during the test but not within 48 h following treatment applications. Insecticide applications were delayed until infestations of bollworm and tobacco budworm larvae in varying stages had become established in the plots.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84711561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
