Prevention and control methods of leaf blight in autumn

Remove diseased leaves

After entering autumn, if diseased leaves are found, the diseased fallen leaves of the plants must be handled in time, and it is best to destroy them to avoid creating a source of infection.

Cultivation management

To strengthen cultivation management, it is best not to use nitrogen fertilizers in a biased manner, and to achieve a balanced use of nitrogen and phosphorus fertilizers. When watering, be careful to avoid waterlogging in the soil. It is recommended to water in small amounts after the soil is dry. Keep the air circulating and do a good job of indoor ventilation to enhance the resistance of plants.

Drug prevention

In the hot and humid environment after the beginning of autumn, regular spraying is necessary to prevent the occurrence of diseases. The best effect is to use 75% wettable powder at 500 to 800 times the concentration. The spraying time is once a week, spray two to three times in a row. If the disease has already occurred, you should use 200 to 300 times diluted 25% carbendazim wettable powder once every 7 to 10 days until the disease is relieved and then stop using it.
