Recent investigations have found that many of the sheds in the sheds are severely affected by eggplant diseases, which is mainly due to inadequate management. It is hoped that the farmers will strengthen their comprehensive management and prevent the infestation of the disease. Eggplant Mushroom Disease, also known as rotten eggplant, occurs commonly in various vegetable areas. Exposed eggplants and protected eggplants can occur. Eggplants can be affected at all stages of their fertility.
Strictly rotating areas should not be rotated with Solanum vegetables. When conditions permit, the rotation should be more than 3 years.
The cultivation of high-riding ridges can be easily planted in drained plots, deep-lying the exposed plots after pulling, and applying more organic fertilizers and phosphorus and potassium fertilizers; cultivation in high ridges is not allowed to flood irrigation, excessive precipitation should be promptly eliminated, and proper cultivating should be adopted. Tear soil.
Sparse planting and interplanting in late-maturing eggplant varieties, plant tall, planted too dense, poor ventilation and light transmission in the field, high temperature, high humidity, canopy closure leads to disease aggravation, and vice versa. Therefore, if the medium-late-maturing varieties are selected, the planting density per acre should be controlled at 1500-2000 strains, or even about 1000 strains, with single-stalked pruning. And on the basis of wide ridges and thin plants, intercropping dwarf cowpea, rapeseed and other dwarf crops can obtain better economic benefits.
Strengthen field management and timely cultivating and weeding, balancing topdressing and pruning, and removing old leaves, yellow leaves, diseased leaves and rotten fruit at the bottom.
Chemical control 1. When the tomato seedlings are planted, use 70% thiophanate-methyl WP or 75% enemy powder to compose 1 : 100 of medicinal soil, and apply 75-100 kg per acre. 2. Irrigation. The initial onset can be used 25% metalaxyl WP 500 times or 80% aluminum phosphate 600 times Irrigation roots, in each near root irrigation liquid about 150 ml, every 7-10 days irrigation. 3. Spray. At the beginning of the disease, it is protected by 1:1:200 Bordeaux spray and can also be sprayed with 50% alfa Mn-Zn wettable powder 500 times, 75% chlorothalonil wettable powder 500 times or 64% anti-virus WP 500 times liquid, etc., sprayed once every 5-7 days, depending on the degree of illness, spray 3-4 times. 4. Dip fruit. When the weather turns fine after continuous rainfall, 70% Mancozeb WP may be used 600 times, plus 25% radomeril WP 800 times to make a mixture. (previously removed old solanum). Although this method is expensive, it works well and can recover most of the losses.
