First, to prevent the main, timely spraying.
For drugs with a residual period of 17-21 days, they are usually sprayed every 15 days. If the rainfall in the middle, depending on the amount of rain, as appropriate, shorten the next spraying days. If heavy rain falls after spraying, it will be sprayed again after sunny weather. If the two adjacent drugs are alkaline or acidic, strict attention should be paid to the interval to prevent acid and alkali neutralization of the two drugs.
Second, see the disease early, timely treatment.
Rainy weather, high temperature and humidity, and the most susceptible to disease, should be observed once a day in the vineyard. See the disease first, that is, symptomatic spraying. The downy mildew can be controlled with 70% of Kepo 600x, 80% of alfa-aluminum 300 times or 1:0.7:180 of Bordeaux.
Third, mainly Bordeaux fluid, adapted to other drugs.
In the process of grape disease prevention, the Bordeaux mixture is mainly used to adapt to other drugs, and the disease prevention effect is very good. Spray 1:0.5:240 times before flowering, 1:0.7:220 dilution after flowering, 1:0.7:200 dilution when grape is inflated, and 1:1:180 after grapes are harvested. Times of liquid, autumn spray 1-2 times 1:1:160 times liquid. If white rot, anthrax and other diseases occur in the middle, symptomatic spraying will occur. These drugs are mostly acidic, with strict control of Bordeaux mixture intervals.
Fourth, the amount of appropriate fertilizer, strong tree potential, increase resistance.
In the rainy season, it will cause the loss of fertility, weaken the tree vigor, and reduce resistance. According to the loss of soil fertility and the growth of the grapes, the amount of fertilizer should be increased. The method of “eat less meals and more meals†should be used to apply the fertilizer to a small amount. Out-of-root fertilizers do more with less. Usually combined with spraying, especially needed, spray alone. 0.5% urea can be added at the time of spraying Bordot's solution. When spraying acidic drugs, add 0.5% urea and 0.3% potassium dihydrogen phosphate. Can also spray the quality of leaf fertilizer. However, the new fertilizer must first be used in small areas and then used in large areas.
5. Releasing soil in time will increase soil permeability.
Rainy seasons, especially heavy rains, and after heavy rains, can cause surface rust in the vineyards, resulting in poor ventilation of the soil, resulting in a lack of oxygen in the root system of the grape, weakened tree vigor, reduced resistance and susceptible to disease. Therefore, cultivating the soil deeper before the rainy season. During the rainy season, we must pay close attention to the rainy days and cultivate the vineyards to increase the permeability of the soil.
Sixth, clear the auxiliary tip to facilitate ventilation.
In the rainy season, the grapes are most prone to longevity and the incidence of shoots is very high. It is necessary to timely pick up the grapes and erase the shoots in time. At the same time, for excessive shoots, we must eliminate some of the shoots, which is conducive to ventilation and light transmission and improve resistance.
7. Clean the garden in a timely manner to curb the spread of the disease.
If there is a disease in the vineyard, it is rainy, hot and humid, and the disease is most likely to spread. Therefore, we must clear the garden at any time and clear out the diseased diseased leaves, diseased branches, and diseased fruits from the garden, and bury or burn them. At the same time, the weeds in the garden should be promptly removed. When cutting the diseased branches and fruit, the scissors should be cleaned and disinfected to prevent cross-infection.
