Aphids are one of the vicious enemies of cotton in life, which endanger plant leaves and tender head tissue, induce germs parasitic, so that abnormal growth of cotton, cotton short stature, reducing the number of bolls, cotton yield and quality decline, resulting in severe cotton seedlings died No income, in addition to strengthening agricultural control, the need to use agents Qiaozhi. Concealed application: with 3% carbofuran granules or 10% phorate (3911) granules in the sowing (incorporated in the nutrient bowl soil) or before irrigation, combined with fertilizers were applied to the roots of cotton, every 1000 m ~ 2 dosage of 1 to 1.5 kg, the use of cotton roots absorbed into the plant body, to control the effect of aphids off.
