Moroxydine hydrochloride vegetable crop virus disease prevention and control pesticide

Abstract

The present invention relates to a moroxydine hydrochloride vegetable crop virus disease prevention and control pesticide prepared by mixing moroxydine hydrochloride, an iridium solution with the mass concentration of 1%, a plant preparation and water in a weight ratio of 1:1:1:1000, and the plant preparation comprises the following components by weight: 0.5 kg of Momordica grosvenori, 0.5 kg of coptis chinensis, 0.5 kg of honeysuckle, 2 kg of ginkgo biloba leaf, 2 kg of isatis root and 1000 kg of water. The beneficial effects are as follows: the moroxydine hydrochloride vegetable crop virus disease prevention and control pesticide has a very significant effect on prevention and control of variety of vegetable virus diseases compared with a single pesticide.

Description

technical field [0001] The present invention and the field of pesticides, in particular, relate to a pesticide for preventing and treating viral diseases of vegetable crops with morpholinidine hydrochloride. Background technique [0002] Virus disease (Mosaicvirus) is one of the main diseases of vegetable crops. For example, cucumber virus disease is mainly caused by cucumber mosaic virus (CMV), tobacco mosaic virus (TMV) and pumpkin mosaic virus infection. The virus survives the winter in the field with the perennial root plants and residual tissues of the diseased plants; it can also survive the winter with the virus carried by the seeds. The virus is mainly transmitted to the host plant through seeds, sap friction, vector insects and field farming operations, and then repeatedly infects. Another example is tomato virus disease, mottled yellow-green or deep-watered leaves appear on the mosaic-type leaves, the veins are transparent, the leaves are slightly shrunken, and th...

Problems solved by technology

[0003] Many years of research have been carried out at home and abroad on the chemical control of plant virus diseases. Although some antiviral agents have begun to enter the practical stage, chemically synthesized agents have disadvantages such as long cycle, high cost, high toxicity, and serious environmental pollution. , far from meeting the requirements of sustainable agricultural development

Moreover, long-term continuous high-dose application of a single pesticide formulation is likely to cause problems such as pesticide residues, environmental pollution, and the development of drug-resistant fungi.

[0004] A single pesticide formulation can effectively inactivate the development of viruses, but it is not effective in eradicating viruses on plants. There are two reasons why a single pesticide formulation is not effective in preventing and controlling plant virus diseases. The activities of various enzymes are significantly reduced. Although the pesticides have effectively inactivated and controlled the occurrence and development of viruses in plants, due to the reduction in the activity of various enzymes in plants, the growth of plants has not completely recovered from the growth arrest state. , so the plant is still susceptible to the disease; secondly, due to the environment in which the plant grows, the time and method of people spraying the drug, the plant cannot absorb the drug well, resulting in the drug not being able to control the spread of the virus in the plant. and passivation
