Example Embodiment

[0016] Combination pesticide composition: hexaconazole and lentinan.

[0017] Mixing ratio: According to mass ratio, 1-30 parts of hexaconazole and 0.5-10 parts of lentinan are mixed.

[0018] Pharmacological effects of hexaconazole:

[0019] Hexaconazole, Mechanism of Action: It is an azole fungicide, a sterol demethylation inhibitor, and has broad-spectrum protective and therapeutic effects on diseases caused by fungi, especially Basidiomycota and Ascomycota. Destroy and prevent the biosynthesis of ergosterol, an important component of the cell membrane of the bacteria, resulting in the failure of the cell membrane to form and the death of the bacteria. Has systemic, protective and therapeutic activity.

[0020] Pharmacological effects of lentinan:

[0021] Mushroom polysaccharide is an effective active ingredient extracted from high-quality mushroom fruiting bodies. The main components of mushrooms are polysaccharides and unsaturated fatty acids, and also contain a large...

Abstract

The invention provides a composite pesticide for preventing and controlling rice sheath blight disease, which comprises hexaconazole and lentinan in a mass part ratio of 1-30:0.5-10. In the invention, the hexaconazole and lentinan are combined for preventing and controlling rice sheath blight disease, and when the composite pesticide is sprayed onto the leaves in different periods of the growth process of rice, the generation of rice sheath blight disease can be inhibited completely. The composite pesticide can improve the antibacterial and antivirus capability of rice plants and therefore increase quality and yield. The composite pesticide is suitable for preventing and controlling rice sheath blight disease and can effectively prevent and control diseases caused by ascomycetes, basidiomycetes and fungi imperfecti.

Description

technical field [0001] The invention proposes a pesticide for preventing and controlling crop diseases in the agricultural field, specifically a combined pesticide for preventing and treating rice sheath blight. Background technique [0002] Rice sheath blight, also known as moire disease, is infected by Rhizoctonia solani and occurs mostly under high temperature and high humidity conditions. The disease makes the rice not heading, or there are more rice grains heading for the heading, and the grain weight decreases. Jinggangmycin and thiophanate-methyl can be used for control. [0003] The fungus mainly overwintered in soil as sclerotia, and also overwintered as mycelium on diseased body or on other hosts such as field weeds. The sclerotia floated on the water surface and mixed with other debris during the spring irrigation in the next spring. After transplanting, the sclerotia adhered to the leaf sheaths of the rice plants near the water surface. The conditions were suit...
