Treatments were replicated 4 times in a randomized complete block design with each treatment plot consisting of 6 m of double-row bed. One week prior to treatment, a single neonate BAW was placed on the center 12 plants in each plot. Treatments were applied with a drop nozzle sprayer using a diaphragm pump driven by a dedicated engine and pulled with an all terracum vehicle. Albuz yellow tip ceramic nozzles delivering 0.45 gpm at the operation pressure of 100 psi were used on a single-row boom. Sprayer configuration was adjusted for adequate coverage, beginning on 10 Oct with 2 over-the-row and 2 side nozzles for the first through fourth application, and adding 2 additional side nozzles with a single overhead for the remaining 3 applications. Delivery rates were 30 gal/acre for the first application, 50 gal/acre for the second through the fourth, and 63 gal/acre for the rest. The surfactant APSA-80 (@0.03%) was added to all 16 treatments and the water control. The NPV formulation, SX-61991, was applied by backpack sprayer because of windy conditions on the second and third application dates, to reduce the risk of cross-plot contamination. Five randomly selected plants from each plot were examined for armyworms 2 days post-treatment. The top 5 leaves of 2 or more growing tips of each of the same plants were evaluated for worm damage. Twenty plants near the center of each plot were randomly selected on 20 Nov and 11 Dec for harvest and evaluation. Pressure was intense during most of the trial with SAW the predominant species. The most significant differences were between chemical and biological treatments. Differences between Bt treatments were less evident, although dose responses were generally consistent for all products.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77504711","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}

Plots were 13.7 X 15.2 m (45 x 50 ft) with 5 replications per treatment in a randomized complete block design. However, the location of 3rd cutting treatments remained the same as that selected for the 2nd cutting. Treatments were applied on 30 Jun to the 2nd cutting and on 11 Aug to the 3rd cutting with a custom built sprayer having a boom length of 4.6 m (15 ft) and flat spray tip nozzles (Teejet 800VS) mounted at 38.1 cm (15 inch) intervals. The system was calibrated to deliver 280.6 liters/ha (30 gal/ acre) at 30 psi at a tractor speed of 5.6 km/hr (3.5 mi/hr). The 2nd cutting treatment was applied when alfalfa stem length was 43.5 cm (17.1 inches) to evaluate control efficacy in a situation where harvest was delayed but stand was susceptible to very heavy PLH feeding activity. The 3rd cutting treatment was applied when stem length was 27 cm (10.6 inches) following harvest of the 2nd cutting. PLH adult abundance was estimated by talcing 10 pendulum sweeps in each plot within 1 day prior to treatments and 2, 7, and 14 DAT. PLH nymph abundance was estimated 7 and 14 DAT when the stage was present in abundance in the untreated plots. Alfalfa stem length was recorded prior to treatments and at 7 and 14 DAT.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"5 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76413015","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}

For both tests, plots consisted of 4 rows (102 cm centers) x 15 m. Treatments were arranged in a randomized complete block design with 4 replications. The test field had been treated previously with Ammo 2.5 EC (0.033 kg [AI]/ha) to stimulate cotton aphid infestations. Insecticides were applied to Test 1 and Test 2 and 18 Jul with a tractor mounted boom equipped with a compressed air system calibrated to deliver 93.6 liters total spray/ha through Teejet X-12 hollow cone nozzles (2/row) at 3.02 kg/cm2. Plots were sampled on 22 (4 DAT) and 25 Jul (7 DAT). Treatment efficacy was evaluated by sampling the plant terminal (all apical shoot growth above and including the first fully expanded leaf). Fifteen and 10 samples on 4 DAT and 7 DAT, respectively, were collected from each plot and held in glass jars. Aphids were washed from the plant foliage onto 300 mesh wire sieves, backwashed onto ruled filter paper (7 cm) and counted using a binocular dissecting scope. These tests received 0.9 cm rainfall on 18 Jul and 1.8 cm rainfall on 19 Jul.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81047962","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}
