Response of cotton (Gossypium hirsutum var. Giza 67), soybean (Glycine max var. Clark), tomato (Lycopersicon esculentum var. Beto 86), sorghum (Sorghum vulgare var. Saccaratum), and corn (Zea mays var. Giza 2) to propanil, bentazon plus propanil, thiobencarb and butachlor, was investigated under field and /or greenhouse. Herbicides were applied over-the-top at different growth stages of plants. Cotton plant at one to three leaf stages were able to tolerate spray drift of 2.4 kg/ha of thiobencarb or 1.45 kg/ha of butachlor. Soybean plants tolerated thiobencarb drift up to 2.4 kg/ha without significant reduction in yields. Foliage injury from either butachlor or propanil (alone or with bentazon) resulted in reduction of yield. Sorghum could tolerate butachlor to a rate of 1.45 kg/ha. It was sensitive to thiobencarb and propanil.
