Embodiment Construction

[0017] Combination pesticide composition: Morpholine guanidine hydrochloride and lentinan.

[0018] Mixing ratio: According to the mass ratio, it is composed of 1-40 parts of morpholinoguanidine hydrochloride and 0.5-10 parts of lentinan.

[0019] By formulating the combined pesticide into an aqueous solution, spraying the surface of the tobacco stems and leaves has a preventive effect on tobacco virus diseases.

[0020] Pharmacological effects of the drugs used:

[0021] Morpholinidine hydrochloride can inhibit virus DNA and RNA polymerase activity and protein synthesis, thereby inhibiting virus reproduction. 1% concentration has obvious inhibitory effect on DNA virus and RNA virus, and has an inhibitory effect on all stages of the virus proliferation cycle.

[0022] Lentinan is an effective active ingredient extracted from high-quality Lentinus edodes fruiting bodies. The main ingredients of Lentinus edodes are polysaccharides and unsaturated fatty acids. It also contains a large amo...

Abstract

The invention provides a combined pesticide for controlling tobacco virus diseases. The combined pesticide is prepared by mixing 1 to 40 parts of moroxydine hydrochloride and 0.5 to 10 parts of lentinan. The combined pesticide controls the tobacco virus diseases by matching the moroxydine hydrochloride with the lentinan, is sprayed on leaf surfaces by stages during growth and development of tobacco, can completely inhibit the tobacco virus diseases and promote disease resistance of tobacco plants, plays a role in improving the quality and yield, and is suitable for controlling the tobacco virus diseases.

Description

Technical field [0001] The present invention proposes a pesticide used for the prevention and control of crop diseases in the agricultural field, specifically a combined pesticide used for the prevention and treatment of tobacco virus diseases. Background technique [0002] Tobacco virus disease is commonly known as tobacco mosaic disease, which is currently the most widespread and common type of disease in tobacco production. At present, there are 16 kinds of tobacco virus diseases that have been discovered in my country, among which the viruses that cause tobacco mosaic disease are mainly three kinds of viruses, TMV, CMV, and PVY. Viral diseases in most areas are mixed with several viral diseases such as tobacco cucumber mosaic virus disease (CMV) and tobacco common mosaic virus disease (TMV), and repeated infections. The rate of diseased plants in the field is generally 20% to 40%, with a weight of 40% to 80%. After tobacco is infected with the virus, chlorophyll is destroye...
