This test was carried out in Santa Bárbara D' Oeste, State of São Paulo, Brazil, to evaluate the action of seven pesticides against the two-spotted spider mite. The treatments were eight with four repetitions. Each treatment utilized 800 m² and had the following characteristics: A - check; B - clofentezine, 250 g; C - f enpropathr in, 150 g; D - binapacryl, 800 g; E cypermethrin plus profenofos, 50 g plus 500 g; F clofentezi ne, 750 g; G - clofentezine , 250 g; H - fenpropathrin, 75 g. The quantities of pesticides above were of active ingredient per hectare. Except in the treatment B, where two applications of clofentezine was performed, all other treatments received only one spray. Endosulfan was added to the experimental pesticides in order to control the cotton boll weevil. The best results were obtained in the treatments that employed clofentezine (treatments B, F and G).
