My opinion on the control of grape rot
Grape rot is a combination of "bacteria + fungi + fruit flies" combined virus. During the color conversion period, due to the conversion of sugar and thin skin, it causes the yeast, bacteria and fruit flies to breed. The characteristics of the disease: First, the fruit becomes soft and light brown, and slowly decays. The second is that there are many fruit flies in the ear, and the rupture of the residual fruit pieces. After the fruit bags are removed, the flies fly wildly. The third is to walk into the orchard and smell a fermented sour smell. Fourth, there are a lot of small white fleas on the ear with serious damage. The rotten granules flow, the infection spreads to the whole ear, and the whole ear rots.
Physical control: Plastic bags or plastic barrels followed by rotten fruit, brought out of the park for drug treatment and buried.
Pharmaceutical treatment: Spray 80% wettable powder 400 times solution + quench 3000ml of 10% EC or 1000mg of Drosophila amine on the front and back of the whole plant and leaves. Spray carefully and carefully.
I have a lot of feelings about the acidosis of grapes. On July 3rd this year, our company's plastic greenhouses had already entered the color change period. At that time, the staff opened the water valve and forgot to turn off the valve. At the time, the water flowed into the greenhouse and a row of Venus non-nuclear grapes was poured. As a result, the fruit rapidly increased, the spikes became compact, and each other became crowded and cracked. The juice was fermented and rotted at high temperatures, and there was a sour smell. The rate of rot fruit was 5 About %, but there are few lines of grapes without irrigation, there is basically no sour phenomenon, so remind friends of fruit farmers not to carry out irrigation during fruit ripening, so as to avoid harm and reduce commodity value.
