Apple to prevent brown spot in the rainy season

In July, there were various degrees of continuous rainy and hot weather in various places, which provided conditions for the occurrence of apple diseases and insect pests. In particular, the prevention and treatment of leaf diseases such as apple brown spot has also reached a critical period.

solution

1. Strengthen cultivation and management, increase tree vigor, and increase tree disease resistance. The orchard with high soil viscosity or high groundwater level should pay attention to drainage and prevent internal hemorrhoids. Reasonable pruning, so that the crown can be air and light to reduce the occurrence of diseases.

2. Apple orchards that do not fight drugs after bagging shall seize the time and fight drugs. In principle, the interval between two times before the bagging and before the bagging shall not exceed 10-15 days.

3. The principle of fighting drugs after bagging. After bagging fight drugs should be controlled within the suction (treatment) + protection sequence, alternating use. Change the old habit of protection + absorption (treatment).

After apple bagging, the rainy weather is frequent. Although many apple orchards have not yet caused apple brown spot, brown spot pathogens have been infected to varying degrees. Therefore, the main antibacterial agents must be treated with antiseptics.

The agents used to control brown spot should be mainly azoles, such as Xize (50% thioxazolol SC) or Mimi Miaixiu (12.5% ​​epoxiconazole SC) or novel (12.5% ​​tebuconazole EW). Such as the effect is very satisfactory, especially serious orchard can be added Tria (46% more resistant manganese zinc WP), the treatment quickly and thoroughly. The control of brown spot should master the interval between medications. If the interval between medications is too long and rainfall occurs, no matter how good the medicine is, the effect is not good.

It is particularly emphasized that if continuous rainfall is encountered, whether or not drugs are used before the rain, it is important to make good use of the time after stopping the rain, make timely supplements to pesticides, and treat mainly pesticides to prevent the occurrence of leaf diseases such as brown spot disease. .
