LEAFMINER CONTROL ON FRESH MARKET TOMATOES IN, SPRING 2002

LEAFMINER CONTROL ON FRESH MARKET TOMATOES IN, SPRING 2002 (E83) TOMATO: Lycopersicon esculentum Miller, 'Agriset' David J. Schuster Gulf Coast Res. & Educ. Ctr. 5007 60th St. E.

Each plot consisted of a single 18 ft row with rows on 6 ft centers. Ambush 2EC was applied at 3.2 oz/acre on 14, 21, 28 Mar, 4, and 10 Apr to try and increase the leafminer population. Experimental treatments were replicated four times in a randomized complete block design and were applied with a 2.5 gal, hand-held CO -powered sprayer on 1 Apr and 28 May. The sprayer was operated at 60 psi and delivered 60 gpa for the first application and 120 gpa for the second application using a single nozzle fitted with a D-5 disk and no. 25 core. The number of leafmines were counted during a 2 min search of each plot on 17, 24 Apr, 1 May, 6 and 12 Jun. The leafminer population was very low for a spring trial. All treatments, except Proclaim on 17 Apr, resulted in fewer leafmines compared to the check two and 3 wk after the first treatment. Agri-Mek still had fewer mines compared to the check four weeks after treatment. No treatments resulted in fewer leafmines relative to the check after the second application. No foliar symptoms of phytotoxicity were observed.
