Embodiment 1

[0030] The 5wt% chitosan oligosaccharide solution is diluted with water to the corresponding application concentration respectively, and the concentration is calculated according to the weight percentage concentration, and is calculated in ppm (parts per million) concentration in the result record, and 50ppm represents the weight percentage in the following result record. The concentration is 0.005%. Water treatment served as a control. The diluted solution is used to treat pepper seeds and pepper plants in stages according to requirements. The seed treatment is seed soaking, and the soaking time is 24 hours. The treatment method in other stages is chitosan oligosaccharide water spray treatment, and the interval of spray treatment is 15 days. Each treatment was observed and tested through 3 experimental fields (667 square meters), and the samples of the treated seeds were counted when the crops grew into 4 leaves after germination. statistics. The percentage of diseased pep...

Abstract

The invention relates to a chitosan oligosaccharide composition for resisting a hot pepper virus disease as well application and a method thereof, and in particular relates to a pesticide composition for resisting a hot pepper virus disease. The pesticide composition comprises chitosan oligosaccharide, wherein the weight percentage of chitosan oligosaccharide is 0.0035%-0.025% of weight of the pesticide composition. The invention also provides application of the pesticide composition comprising chitosan oligosaccharide for preventing and treating the hot pepper virus disease. The pesticide composition is characterized in that the chitosan oligosaccharide is 0.0035%-0.025% by weight of the pesticide composition comprising chitosan oligosaccharide. By using the composition provided by the invention, the important problem of resisting the hot pepper virus disease is solved, especially, after the pesticide composition comprising chitosan oligosaccharide is used for treating the seeds and plants of hot pepper, the hot pepper virus disease is resisted, crops are not damaged, and no pesticide is remained.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a control composition and a control method for capsicum virus disease, in particular to a chitosan oligosaccharide composition for resisting capsicum virus disease and its use and method. Background technique [0002] Capsicum virus disease, also known as mosaic disease, toxin disease, mad disease, etc., has become increasingly serious all over the country in recent years. It is one of the most important diseases of pepper, and it occurs in both spring and autumn, with autumn pepper and autumn delayed pepper suffering the most serious diseases. Due to the hazards of viral diseases, the production of common sweet peppers has decreased by 5%-10%, and that of long-horned peppers has decreased by about 10%. [0003] Capsicum virus diseases are mainly caused by cucumber mosaic virus and tobacco mosaic virus. Tobacco mosaic virus can survive for a long time in the dr...
