Efficient pesticide for red spiders

Abstract

The invention discloses an efficient pesticide for red spiders. The efficient pesticide for red spiders is prepared from the following raw materials in parts by weight: 5-10 parts of fructus cnidii, 4-8 parts of fructus forsythiae, 3-5 parts of camphor, 3-7 parts of potassium oleate, 4-9 parts of nekal, 2-6 parts of rhododendron molle, 1-5 parts of anemone vitifolia, 3-6 parts of polyoxyethylene, 3-9 parts of avilamycin, 2-6 parts of fructus meliae leaves, 2-7 parts of butachlor, 1-3 parts of pendimethalin, 2-6 parts of propylgallate, 4-8 parts of diafenthiuron, 1-3 parts of an anti-blocking agent and 4-9 parts of octadecanol polyoxyethylene ether. The efficient pesticide for red spiders has the beneficial effects of effectively killing the larva of red spiders, bringing a certain asphyxia function to adult red spiders and having good insecticidal efficacy.

Description

technical field [0001] The invention relates to a high-efficiency pesticide for spider mite. Background technique [0002] Red spiders mainly harm various vegetable crops such as Solanaceae, Cucurbitaceae, Legumes, and Liliaceae. There are many species of spider mites on jujube trees, and the dominant species in jujube-grain intercropping jujube orchards is Tetranychus truncation, which parasitizes widely, including jujube trees, cotton, corn, beans and various weeds and vegetables. The red spider sucks the plant juice on the back of the leaves as adults and nymphs, and the surface of the damaged leaves is yellow-white spots. In severe cases, the entire leaves turn yellow, wither and fall off, and large areas of the field appear to be on fire, and leaves fall early. Affect leaf photosynthesis and growth, reduce yield. Usually the lower leaves are affected. Gradually spread upwards. Therefore, red spiders are very harmful to crops and cause a large reduction in crop prod...
