Control Measures of Brown Rot of Zucchini

Zucchini brown rot, commonly known as "flower rot", "rotten egg." Often cause a lot of young melon rot, severely reduced production. The pathogenic bacteria invade young fruit and invade many of the peduncles, thus spreading to whole guars. Diseased melon outside brown, rapid soft rot, humidity, diseased parts of melons grow white Jin Mao, which can be seen faintly in the top of M. villosa gray to black head. Finally, the young rots are all rotted, commonly known as "fruit rot" and "rotten egg." In a few cases, mature fruits can also be browned locally and soften and rot. The stalk and petiole were immersed brown soft rot. In the prevention and control can take the following measures.

First, the seed soaked is selected from disease-resistant and coated seeds. If it is not coated, it should be sterilized with seed dressing agent or seed soaking agent. When soaking, soaking in warm water of 55°C for 15 minutes, strengthen the ventilation and disperse moisture. Greenhouses can be cultivated during the summer period, the sheds are filled with water, the ground is covered with a plastic film, covered for several days, and sterilized by high temperature.

Second, rational and close planting in time to remove disease vines, diseased leaves, diseased plants, and brought out of the field burned, diseased hole application or quicklime. And pay attention to more than two years of rotation with non-melon crops.

Third, the irrigation and moisture-proof sorghum film cultivation, reasonable irrigation, timely release after irrigation. Prevention of flooding in flooding leads to excessive humidity in the protected area.

Fourth, picking the sick flowers and young fruits after the fruit set up timely removal of residual flowers, see the fruit after the removal of deep processing. When the flowers, stems, and petioles of the squash were affected, the residual flowers were promptly removed, and the infected parts were smeared with 50-fold paste at the site of the disease.

5. Chemical control After sowing, the soil is covered with pesticide and sprayed with a sterilizing agent before transplanting. This is an important measure for preventing and controlling diseases and insect pests; 70% Mancozeb WP can be used 500 times, 50% flutter. Hydrate 1000 times or 77% can kill WP 400 times spray control, protection can be used 45% chlorothalonil smoke agent with 200 to 250 grams per acre smoked.
