The main reason for the fruit crack is that the growth rate of the pulp exceeds the growth rate of the peel. So what is the result of this? First, because the tea yellow scorpion harms the young fruit, the eggplant pulp is not long inside, so that the final pulp will crack the peel. The second reason is that during the process of fruit enlargement, due to sudden watering or rain after drought, the pulp absorbs too much water and grows too fast over the peel to cause cracking.

In terms of prevention and control, we must strengthen the prevention and control of sassafras, and we must eradicate weeds in the field and reduce the source of insects. It is found that the damage of the tea scutellaria is controlled by using 1.8% avermectin EC 1500-2000 times liquid or 20% double nail emulsifiable oil 1000-1500 times. The second is to properly irrigate the fruit during the expansion period, so that the soil is not too dry or too wet. Linyi Fertilizer Network Copyright
