Embodiment Construction

[0018] Combined pesticide composition: composed of kasugamycin and lentinan.

[0019] Mixing ratio: According to the mass ratio, 1-20 parts of kasugamycin and 0.5-10 parts of lentinan are mixed.

[0020] Pharmacological effects of kasugamycin: kasugamycin, an agricultural fungicide. It has excellent control and treatment effects on rice blast.

[0021] Kasugamycin is also called kasugamycin; (5-amino-2-methyl-6-(2,3,4,5,6-hydroxycyclohexyloxy)tetrahydropyran-3-yl)amino-α - imidic acid. kasugamycin; kasumin; kasurabcide; kasumin-bordeaux; KS melting point: 236-239°C (decomposition); hydrochloride: 202-204°C (decomposition). Pure product is white crystal; hydrochloride is white needle or flaky crystal with sweet taste.

[0022] Kasugamycin is a biochemical pesticide that can inhibit rice blast virus. Therefore, foliar spraying at different stages of the rice growth cycle can control the reproduction and spread of rice blast pathogens, thus producing the effect of preventing...

Abstract

The invention provides a medicament for controlling crop diseases in the field of agriculture, in particular a combined pesticide for controlling rice blast. The combined pesticide is prepared by mixing 1 to 20 parts of kasugamycin and 0.5 to 10 parts of lentinan. The kasugamycin is matched with the lentinan to control the rice blast, and the combined pesticide is applied to leaves in the rice growth process by stages, can completely inhibit the rice blast and improve antibacterial and antiviral capabilities of rice plants, has the function of improving the quality and yield, and is suitable for controlling the rice blast.

Description

technical field [0001] The invention proposes a pesticide for preventing and controlling crop diseases in the agricultural field, in particular a combined pesticide for preventing and controlling rice blast. Background technique [0002] Rice blast is one of the important diseases of rice, which can cause a large reduction in yield, and in severe cases, the yield can be reduced by 40% to 50%, and even the grains cannot be harvested. The disease occurs everywhere, most of which occur in the leaves and nodes, and can cause different degrees of yield reduction after the occurrence, especially the early and severe occurrence of panicle blast or knot blast, which can cause white ears and even yield. Currently, rice blast can occur in any region and in any season. [0003] Symptoms, also known as rice fever, fire blast, kowtow blast. Distributed in various rice areas across the country, it mainly damages leaves, stems and ears. Due to different damage periods and parts, it can ...
