Although eggplants have a slightly bitter taste, they are still a kind of vegetable that everyone likes. Greenhouse eggplants are prone to diseases, and bacterial leaf spot is one of the popular ones. So, how to prevent eggplant bacterial leaf spot? Let’s have a simple understanding and understanding of this issue together, hoping that the following points will be helpful to everyone!

To prevent the damage of pests, the first step should be to remove the pathogen, select high-quality, disease-free seeds, and need to soak the seeds in 56℃ warm water until the room temperature and then soak for 24 hours, then pick them up to dry and place them in a standard temperature of 30-32℃ to germinate, and plant when the sprouts grow to 3mm. In addition, medical equipment such as streptomycin sulfate or chloramphenicol at a concentration of 500 times can also be used to soak the seeds for 12 hours, clean them after soaking, and then germinate and plant. Eggplants like heat and high temperature, and like humidity but are not resistant to waterlogging. After it rains, good drainage should be carried out to reduce the infection of pathogens. Prevention should be carried out before the outbreak, and 72% streptomycin sulfate solvable granule agent at a concentration of 4000 times or 56% Kaoqingshan Green Microgranule Agent at a concentration of 800 times, 47% Jia Renong wettable powder at a concentration of 1000 times, and 30% alkaline copper sulfate (Green YuYangBao) suspension at a concentration of 400 times can be sprayed.

It is necessary to deal with the symptoms in time before adopting the treatment method, therefore, farmers should also understand the harmful symptoms of this pest. Bacterial leaf spot mainly damages leaves, stems, and fruits. The symptoms that appear at different locations will also be different. When the leaves are infected, they initially appear as brownish water-soaked small spots, which are polygonal or irregular, and are easy to cause holes or cracks in the leaves. After the leaf stem is damaged, it shows water-stained light brown streaks, which are prone to longitudinal cracks in the later stage. The damage to the fruit is serious, and the small spots will develop into real spots, and the fruit will become water-soaked soft rot. When the humidity is high, the rind of the watermelon will be damaged, and the seeds and flesh of the watermelon will be exposed, leading to the entire fruit rotting and falling off, which will directly affect the yield of the fruit.

Eggplant bacterial leaf spot can immediately affect the yield and quality of melon farmers, therefore, it is necessary to grasp the methods of preventing eggplant bacterial leaf spot, so that even if the pest occurs, melon farmers can carry out immediate rescue to reduce the reduction in yield. According to the habits of eggplants, innovative management of the melon garden should be carried out.

This is the characteristic of eggplant bacterial leaf spot shared with everyone today, hoping you can integrate and do a good job in the prevention of eggplant bacterial leaf spot.
