1. First of all, do a good job in the prevention and control of pests and diseases. Focus on the prevention and control of anthracnose leaf blight and brown spot disease, and at the same time prevent bitter pox disease caused by calcium deficiency in fruit trees, red spot disease caused by bagging and insect pests such as red spiders, aphids, leaf roller moths, leaf miners, and stinging moths. After the rain, go to the orchard in time to inspect and spray in time.
The prevention and control suggestions for anthracnose leaf blight are as follows, for the reference of fruit farmers: (1) Pharmaceutical formula: you can choose to use the protective fungicide 50% iprodione 1000 times solution, plus the systemic fungicide Riyoujiatuo 800~1000 times, or 25% bromochlor 800~1200 times spray treatment. (2) If the occurrence is heavier, 60% sodium dichloroisocyanurate can also be used to spray the ground before application to reduce the source of bacteria in the field.
Note: Due to the rapid infection, large sporulation and acute onset of anthracnose leaf blight, the application interval should be shortened to 4~5 days, and the drug should be used continuously for 2~3 times; Be careful to rotate the use of agents; When spraying, we must pay attention to improving the degree of atomization of pesticides, improve the quality of spraying, so that branches and leaves are evenly used, and at the same time, pesticides should be applied to the ground.
2. Drain water in time. When there is stagnant water in the garden, the fruit trees will be soaked for a long time, which will cause a large number of root deaths due to lack of oxygen. Therefore, it is necessary to drain the water in time, and turn the ground when the soil is slightly dry to improve the soil permeability.
3. Check the fruit bag. Check whether the mouth of the fruit bag is firm, drain the stagnant water in time, expand the air vent, and prevent and control the sunburn of apples and other diseases caused by high temperature and high humidity.
4. Mow the grass at the right time. When it rains, weeds in the garden will inevitably grow quickly, so cut the grass at the right time according to the height of the grass. Avoid excessive weeds that lead to poor ventilation of the orchard, which will aggravate the spread and infection of diseases.
5. Top dressing. Orchards that have not been fertilized in the early stage can take advantage of this rainfall for top dressing. The amount of nitrogen fertilizer should be strictly controlled, mainly high potassium fertilizer, with medium and trace element fertilizer.
