Embodiment 1

[0021] Dilute the 5% chitosan oligosaccharide solution with water to the corresponding application concentration. The concentration is calculated according to the weight percentage concentration. In the result record, it is calculated as ppm (parts per million) concentration. In the result record below, 50 ppm means weight percentage The concentration is 0.005%. Clean water treatment was used as a control. The diluted solution was used to process the cabbage in the early onset of the diamondback moth in stages according to requirements, and the interval of spray treatment was 7 days. Each treatment was observed and detected through 3 test fields (100 square meters), and the disease development of the diamondback moth in each test field was counted separately. The timing of applying the chitosan oligosaccharide solution to the diamondback moth is that the diamondback moth eats the cabbage. The number of plants with insect populations accounts for 3±0.25% of the total cabbage pl...

Abstract

The invention relates to a chitosan oligosaccharide composition for killing diamond back moths, its application and method. Concretely, the invention provides a pesticide composition for killing diamond back moths, comprising 0.004-0.022 wt% of chitosan oligosaccharide. The invention also provides an application of the pesticide composition containing chitosan oligosaccharide for controlling diamond back moths and a method for applying the composition containing chitosan oligosaccharide in controlling diamond back moths. According to the invention, the important problem of killing diamond back moths is solved, especially the pesticide composition containing chitosan oligosaccharide can kill diamond back moths and has no phytotoxicity to crops and no pesticide residues after using the pesticide composition in treating the crops having the diamond back moth disease, so that the environmental control of diamond back moths is realized.

Description

Technical field [0001] The invention belongs to the field of agricultural chemistry, and particularly relates to a control composition and a control method for the diamondback moth, and specifically relates to a chitosan oligosaccharide composition for killing the diamondback moth and its use and method. Background technique [0002] Plutella xylostella L., also known as hanging silkworms, belongs to the Lepidoptera (Lepidoptera) family Plutella. It is a worldwide pest. It originated in the Mediterranean region and has more than 40 species of hosts. It mainly damages cross flowers. Among them, cabbage, cauliflower, cabbage, cabbage, radish, rape, etc. suffer the most. They can also harm potatoes, onions, and some ornamental plants, such as violets, wallflowers, and isatis root in medicinal plants. In my country, since the diamondback moth became the main pest of cruciferous vegetables in the 1970s, it has been severely occurring in southern provinces such as Guangdong, Hainan, Fu...
