Composition for controlling botrytis cinerea of broccoli and preparation method thereof

Abstract

The present invention relates to the field of pesticides, in particular to a composition for controlling botrytis cinerea of broccoli, which comprises the following raw materials in parts by weight: 10 to 20 parts of callicarpa bodinieri, 12 to 18 parts of gentiana macrophylla, 12 to 18 parts of Herba Pteridis multifidae, 2 to 8 parts of radix semiaquilegiae, 12 to 18 parts of commelina communis,10 to 20 parts of manyleaf paris rhizome, 12 to 18 parts of Belamcanda sinensis, 2 to 8 parts of Flos Eriocauli, 10-20 parts of Chinese holly, 12-18 parts of tobacco, 8-12 parts of fructus piperis longi, 8-12 parts of polygonum cuspidatum, 3-9 parts of fructus trichosanthis, 8-12 parts of reed rhizome, 6-8 parts of complex bacteria, 10-20 parts of complex amino acid, and 8-12 parts of multi-vitamin. The composition of the invention cannot cause harm to the broccoli, and at the same time, the composition has the good prevention and control effect on the botrytis cinerea of broccoli, the incidence of the botrytis cinerea of broccoli is controlled at 1.23%, the total effective rate of the broccoli infected with botrytis cinerea is more than 95%, and the control effect is remarkable.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a composition for preventing and treating gray mold of broccoli and a preparation method thereof. Background technique [0002] The nutrients in broccoli are not only high in content, but also very comprehensive, mainly including protein, carbohydrates, fat, minerals, vitamin C and carotene. According to analysis, every 100 grams of fresh broccoli curd contains 3.5-4.5 grams of protein, which is 3 times that of cauliflower and 4 times that of tomato. In addition, the mineral components in broccoli are more comprehensive than other vegetables, and the contents of calcium, phosphorus, iron, potassium, zinc, manganese, etc. are very rich, much higher than that of cabbage that belongs to the cruciferous family; the anti-cancer effect of broccoli It is an important content studied by scientists in Western countries and Japan in recent years. On the list of anti-cancer vegetables released b...

Problems solved by technology

Symptoms on petioles are similar to lesions on stems, but they are long strips with dark green mold. Currently, broccoli is treated with procymidone, thiophanate-methyl, and iprodione at the seedling stage. For spraying, use 41% polyastatine pyrimethanil water emulsion 800 times liquid + 10-15g or Bixiu Dan (chlorobromoisocyanuric acid) 30g or propiconazole 10ml or 40% procymidone wettable powder 15- 20g or 20g of methotendazim, mixed with 15kg of water, once every 3-5 days for treatment after the onset of the disease, although it can achieve a certain effect, but the traditional spraying of the drug will cause drug residues, which will cause harm to the human body. The effect of disease control is not significant. A series of problems are more harmful. Therefore, effective improvement of the control of traditional broccoli gray mold is the focus of current research.
