Composition for treating root knot nematode disease of Momordica grosvenori, and preparation method thereof

Abstract

The invention relates to the field of pesticides, and especially relates to a composition for treating the root knot nematode disease of Momordica grosvenori. The composition comprises, by weight, 20-30 parts of derris root, 8-12 parts of Radix Euphorbiae Ebractealatae, 10-20 parts of Flos Genkwa, 8-12 parts of tobacco, 10-20 parts of Acorus calamus Linn, 6-9 parts of Common Threewingnut Root, 8-12 parts of Polygonum glabrum, 10-20 parts of Chinese Azalea Flower, 15-25 parts of Peganum harmala L., 12-18 parts of Bidens pilosa L., 8-12 parts of Piper cubeba, 10-20 parts of Common Carpesium Fruit, 8-12 parts of composite amino acids and 6-8 parts of mixed bacteria. The composition has a remarkable treatment effect on the root knot nematode disease of Momordica grosvenori, the average total marked effective rate is 98% or above, the average total cure rate is 95% or above, and the root knot nematode disease of Momordica grosvenori can effectively control the incidence of the root knot nematode disease of Momordica grosvenori, maximally treats the root knot nematode disease of Momordica grosvenori, is of great significance to treat the root knot nematode disease of Momordica grosvenori, solves defects brought by traditional medicine therapy, and reduces the medicine residues on the Momordica grosvenori.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a composition for treating root-knot nematode disease of Luo Han Guo and a preparation method thereof. Background technique [0002] Luo Han Guo, the fruit of perennial vines of the Cucurbitaceae family, is also known as Lahan Guo, False Bitter Gourd, Light Fruit Wood Turtle, Jinbuhuan, Luo Hanbiao, and Naked Turtle. It is known as the "fairy fruit". It blooms and bears fruit in autumn. It is one of the first batch of medicinal and edible materials approved by the country. Its main function is to relieve cough and reduce phlegm. The nutritive value of the fruit is very high, rich in vitamin C (400 mg to 500 mg per 100 grams of fresh fruit), glycosides, fructose, glucose, protein, lipids, etc. Luo Han Guo is the first batch of medicinal and edible products announced by the Ministry of Health. The precious Chinese herbal medicine contains mogroside which is 300 times sweeter than sucrose...

AI Technical Summary

Problems solved by technology

After the nematode parasitizes, the function of the root system is destroyed, which makes the aboveground part of the plant grow weak and turn yellow, which affects the yield. The traditional treatment method uses traditional commercially available medicaments, which not only has poor treatment effect, but also causes damage to the roots of Luo Han Guo, making the tree body The drug residues are serious hazards. Therefore, the effective improvement of the traditional treatment of root-knot nematode disease of Luo Han Guo is the focus of current research.
