الوصف: The insecticide trials were conducted in Lancaster County, Landisville, Pa. Certified 'Katahdin' seed potatoes were planted on 3 May with 9 inch spacing between plants and 3 ft between rows. Plot size was 4 rows by 25 ft with 2 border rows arranged in a randomized complete block design with 4 replicates. Temik 15 G (1.0 lb [AI]/acre) was applied in furrow at planting for all treatments. The control received Temik at planting, however, no specific foliar insecticide was applied to the plot. The entire field was sprayed with 0.1 lb [AI]/acre permethrin on 8 and 15 Jun to protect the emerging plants from adult Colorado potato beetle (CPB). An application of Asana 0.0375 lb Al/acre was applied on 5 Jul to reduce the high density of CPB. Experimental treatments were applied on 30 Jun, 5, 22, 25 Jul, and 4 Aug. The entire field was sprayed again with Asana (0.0375 lb Al/acre) on 9 Aug. Border rows were sprayed with Pydrin (0.2 lb Al/acre) and piperonyl butoxide (PBO) (0.4 lb Al/acre). A George White boom sprayed delivering 30 gal/acre at 27 psi was used to spray the plants. A hand held COa pressurized spray was also used to apply the materials. Thirty gal of spray material was delivered/acre at 27 psi also with the hand sprayer. Sprays were applied by the tractor mounted sprayed at 3 mph; a Ty-18 type nozzle with 50 mesh screens were used. Five or 10 stems/plot were sampled before the spray was applied. Counts were taken 24-72 h following application with all stages of CPB being sampled. Average daily temperatures (°F) were 62.6° for May, 70.6° for Jun, 77.7° for Jul, and 75.2° for Aug. Departure from average was 8.8 degrees for this period. Rainfall totals were 5.99 inches in May, 1.16 inches in Jun, 7.97 inches in Jul, and 4.37 inches in Aug.
