Spider Mite Control on Cotton, 1985

'Paymaster 145' was planted on 7 May and grown by standard methods. The test area was a randomized complete block with 8 row plots 40 ft long. The test insecticides were applied in 5 gal/acre with a Hi-Boy sprayer. Plots were infested on 10 Jul with a Yazoo City, Mississippi strain of two-spotted spider mite known to be resistant to chlorinated hydrocarbon, organophosphate, and carbamate miticides. All plots except Capture 0.05 lb (AI)/acre plots were over-sprayed with 0.05 lb (AI)/acre Ammo to induce mite build-up. Twenty-five leaves on the 6th node from the terminal were examined for mite infestation on 1 Aug, and 25 leaves on the third node from the terminal on 6 and 15 Aug.
