Problems solved by technology

In production, most of the control drugs are compound agents, which are only suitable for the control of 1-2 instar larvae. The persistence period is short, and the effect on older instars is poor. Farmers need to apply pesticides multiple times, and there is a lack of long-lasting and quick-acting agents.

Abstract

The invention provides a biological insecticide for preventing and controlling high mountain cnaphalocrocis medinalis guenee, and relates to the field of insecticides. The biological insecticide is prepared from the following raw materials in parts by weight: 33 to 42 parts of SYP-9080 (Silvchongxian'an), 12 to 23 parts of sodium fluosilicate, 15 to 25 parts of deltamethrin, 10 to 15 parts of nicotine, 8 to 14 parts of rhizoma cyrtomii, 5 to 10 parts of ruby sulfur, 20 to 35 parts of protein-degradation enzyme and 18 to 25 parts of octadecyl sodium sulfate. In the formula, the protein-degradation enzyme can damage the body structure of the cnaphalocrocis medinalis guenee, and act through being matched with the rhizoma cyrtomii and the ruby sulfur; the cnaphalocrocis medinalis guenee at different age levels can be killed; the drug effect durability is high; meanwhile, side effects cannot be generated on rice.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a biological insecticide for controlling alpine rice leaf rollers. Background technique [0002] The rice leaf roller is one of the common pests of rice, which belongs to the family Lepidoptera. Injury at the tillering stage of rice affects its normal growth; damage in the middle and late stages affects the yield more obviously, especially the flag leaf damage in the later stage, resulting in an increase in grain rate and serious loss. The eggs are scattered on the leaves, usually on the back of the leaves. The newly hatched larvae climb to the tip of the leaf and roll the leaves to feed, and the slightly larger larvae drill into the leaf center, the leaf sheath or the leaf surface to bite the mesophyll, and spin the silk to separate the leaves. Both sides of the vertical roll knot. After the buds are formed, they eat the mesophyll and the upper epidermis along the veins in the buds...
