Problems solved by technology

Although the bagged orchards still continue to use drugs, due to the natural barrier protection of the fruit bags, even if systemic fungicides are applied, their efficacy often cannot reach the lesion on the fruit surface due to the limited transmission distance. The problem of apple and other fruit fruit diseases represented by apple black spot disease is quite prominent

Abstract

The invention discloses a reagent for prevention and treatment of fruit disease of bagging fruit. The raw material of the reagent consists of chloramines T 50 percent to 80 percent, diatomite 11 percent to 25 percent, stearic acid 3 percent to eight percent, shellac 5 percent to 13 percent and hydroxypropyl methyl cellulose 1 percent to 4 percent. The invention also discloses the preparation method for the reagent which is as follows that three different particles are prepared with the formula according to different ratio so that the particle can release germicide at different time and disease prevention for a long time can be achieved. According to the characteristics of bagging fruit disease occurrence, the reagent provided by the invention changes traditional method for medicine application, not only reducing medicine application cost, but also improving prevention efficiency, increasing harvest level and commodity rate and reducing environmental pollution, moreover, win-win resultcan be achieved.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a medicament for preventing and treating diseases in the growth period of bagged apples, pears, grapes and other fruits and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, consumers pay more and more attention to the health and safety of fruit products. Bagged apples, pears, grapes, etc. are popular among consumers because of their large size, clean fruit surface, bright color, less disease and insect spots on the fruit surface, tender yellow and sweet flesh, and less pesticide and heavy metal residues. In the current situation where ordinary fruits are difficult to sell, bagged apples are not only popular, but also sold at a high price, and the economic benefits are very significant. However, after the apples are bagged, due to changes in the micro-regional ecological environment such as light and air permeability, the fruit...
