Abstract

The invention provides a biological insecticide for preventing and controlling rice leaf rollers, and belongs to the technical field of pesticides. The biological insecticide for preventing and controlling the rice leaf rollers is prepared from, by weight, 10-30 parts of aglaia odorata flowers, 10-30 parts of fructus quisqualis, 5-20 parts of needle juniper, 5-20 parts of herb of pilea notata, 5-20 parts of cuculus canorus, 5-15 parts of inula flowers, 3-12 parts of vernonia anthelmintica, 3-12 parts of elm bark, 3-12 parts of radix stemonae, 5-10 parts of allicin and 1-5 parts of a biological microbial agent, wherein the biological microbial agent is prepared from, by mass, 25%-35% of bacillus thuringiensis, 30%-40% of bacillus licheniformis and 35%-45% of streptomyces jingyangensis. According to the insecticide, the materials are environmentally friendly, no harm is generated to rice, the rice leaf rollers can be efficiently killed, the disease resistance rate can reach 100%, and no insecticide resistance is generated if the insecticide is used for a long term.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a biopesticide for controlling rice leaf rollers and a preparation method thereof. Background technique [0002] The rice leaf roller [Cnaph alocrocis medinalis (Guenee)] belongs to Lepidoptera and belongs to the Mothidae family. It is a migratory pest that harms rice in Southeast Asia and Northeast Asia. Under natural conditions, the host has not been found to feed on other plants that have completed generations except rice. The rice leaf roller mainly damages rice leaves with larvae and affects the growth and yield of rice groups: from the tillering stage to the heading stage, the newly hatched larvae feed on the upper epidermis and green meat leaf tissue in the crevices of the young leaf sheath near the heart leaf or the heart leaf, After entering the second instar, it climbs to the vicinity of the leaf tips, spins silk and rolls rice leaves into bracts, and hi...
