Emulsion in water of pesticide composition for controlling cotton aphids and thrips

Abstract

The invention relates to a pesticide composition, and especially relates to an emulsion in water of the pesticide composition for controlling cotton aphids and thrips. The emulsion in water of the pesticide composition for controlling cotton aphids and thrips comprises the following components in percentage by weight: 5-20% of Guadipyr, 5-20% of cyhalothrin, 10-15% of solvent, 4-10% of an emulsifier, 0.2-0.5% of a defoamer, 5-10% of an anti-freezing agent, 2-6% of a disintegrating agent and the balance of water. By compounding the Guadipyr and the cyhalothrin, the resistant cotton aphids can be effectively controlled, the control efficiency is superior to the reference, the lasting period is long, the control effect is up to 90%, and no phytotoxicity is caused to the target crops in the experimental drug scope. According to the emulsion in water of the pesticide composition for controlling cotton aphids and thrips, the defects that the cyhalothrin is relatively bad in environmental friendliness and the Guadipyr is relatively bad in fast-acting property and relatively slow in drug action can be effectively solved.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an aqueous emulsion of the pesticide composition for controlling cotton aphids and thrips. Background technique [0002] Piercing-sucking pests are a large group of important economic pests such as cotton, such as cotton aphids, thrips cotton, leafhoppers, Lygus cotton, spider mites, planthoppers, whiteflies, [0003] The needles on the upper and lower jaws alternately penetrate into the tissue of the plant and suck the juice, resulting in pathological or emergent damage, resulting in dwarf cotton seedlings, smaller leaves, green and red leaves, spots and nicks on the leaves, and even the whole plant withers or die; most species are viral diseases and phytoplasma disease vector insects, which bring secondary diseases to crops and cause heavy losses of cotton in my country every year. [0004] Kungfu permethrin, English name cyhalothrin, molecular formula C 23 h 19 CIF 3 NO 3 , the c...

AI Technical Summary

Problems solved by technology

The results show that Pentetamicloguanidine has the characteristics of high efficiency, low toxicity and good safety, has both the structural characteristics of neonicotinoid insecticides and sodium ion channel inhibitor insecticides, and has a wide spectrum of insecticidal properties. With the characteristics of multiple targets, the product has a good control effect on aphids, planthoppers, cotton bollworms and other piercing-sucking mouthpart pests, but the product has poor quick-acting and slow-acting effects
