Problems solved by technology

In Queensland and other large-scale banana planting areas in Australia, during the epidemic period, Dili demineralized oil is used for aircraft low-volume spraying control, spraying once every 15-20 days, and a total of 8-10 sprays per year, which can effectively control the damage of the disease, but In case of bad weather, if the pesticides cannot be sprayed in time, the disease will become popular.
[0004] Before the implementation of the present invention, there were the following difficulties in the prevention and treatment of brown-margined gray spot of bananas: the widely used pesticide is imported pesticide Dilitox, which is expensive by import, and the cost of prevention and treatment is high; Medicinal properties

Embodiment 1

[0010] Pesticide for preventing and controlling gray leaf spot disease of banana, consisting of triadimefon: 8%, mancozeb 20%, dispersant: 2%, wetting agent: 1%, stabilizer: 1%, filler: balance, Mixed compound. The dispersing agent is 2% of sodium naphthalene sulfonate formaldehyde condensate; the wetting agent can be selected from 1% of pulling powder; the stabilizer can be selected from 1% of calcium carbonate; the filler can be selected from the balance of kaolin. The preparation method is composed of the following steps: drying and cooling the kaolin, then compounding the formula materials triadimefon, mancozeb, sodium naphthalene sulfonate formaldehyde condensate, pulling powder, calcium carbonate, and kaolin, and grinding them finely by a pulverizer. , Mix evenly, after sampling analysis, packaging after qualified. Use 1000 times liquid of the preparation to prevent and control banana brown edge gray spot disease, some of the agents form a protective layer on the leaf s...

Abstract

The invention discloses a pesticide against banana sigatoka leaf spot disease, with the proportion (weight percentage) as follows: 8-15% of triadimefon, 10-20% of mancozeb, 2-5% of dispersant, 1-5% of wetter, 1-5% of stabilizer, and rest of filler. The preparation method is to dry and cool the filler, blend the ingredients, mill and uniformly mix the ingredients by omnipotent disintegrator, package the qualified mixture after sampling analysis. The invention has the advantages of 1 good effect for banana sigatoka leaf spot disease without easily causing drug resistance after been used repeatedly, 2 long last and highly effective efficacy, and 3 low cost.

Description

technical field [0001] The present invention relates to a pesticide, in particular to a pesticide for preventing and treating banana brown edge gray spot disease. Background technique [0002] Banana brown edge gray spot is common in Hainan and other banana planting areas in my country, and it is an important foliar disease that harms bananas. Banana brown edge gray spot disease is difficult to prevent and control, and the degree of damage is becoming more and more serious. The damage caused by the damage is generally 30-50%, and the quality of banana fruit is reduced, resulting in huge economic losses. It has become a hindrance to my country's banana planting industry one of the important factors of development. [0003] In 1997, Lai Yuexian and others proposed to take comprehensive control measures, based on cultivation and disease prevention, and chemical control as the center to achieve the purpose of controlling the expansion and spread of the disease. It has a good pr...
