Leafminer Control on Celery, Spring, 1981

Celery was transplanted Apr 15 into Lauderhill muck soil on the University of Florida, Agricultural Research and Education Center’s farm in Zellwood, FL. Treatments were applied to single row plots 15 ft long (36 inch row spacing and 7 inch plant spacing) and replicated 5 times in a randomized complete block design. Blocks were separated by weed-free 10 ft alleys. The sprays were applied with a CO2 pressurized, 2.5 gal, B & G sprayer. SD-52618, Vydate, GS Mixture and the 0.5 and 1.0 rates of Monitor were applied as foliar sprays with a boom and 1 overhead and 2 drop nozzles with D3 orifice plates and #45 cores. The delivery rate was 50 gpa with a boom pressure of about 45 psi and a speed of 3 mph. The 2.0 lb rates of Monitor and Orthene were applied as a 4 inch band to the soil at the base of each side of the celery plant. The delivery rate was 119 gpa using a single nozzle with a D6 orifice plate and #56 core, a boom pressure of about 45 psi and a speed of 3 mph. RH-9358 and CC-11242 granules were applied as a 10 inch band over the top of the celery plants using a calibrated hand-held granular applicator.
