Early prevention and early management of eggplant brown streak disease

The eggplant brown spot disease pathogens overwinter on seeds or diseased plant residues, mainly by conidia, which are transmitted by wind, water, insects and field operations. After the seedlings are susceptible to the disease, brown to black fusiform or elliptical lesions are produced at the base of the stem near the ground, and the depression is slightly depressed. In the adult stage, the leaves form white small spots, which gradually expand into irregular shaped lesions. The edges are dark brown and the middle is light yellow. Many small black spots are formed on them, which are arranged in a wheel pattern or scattered. The fruit is susceptible to the disease. Initially, it forms a brown lesion on the surface. It is round or elliptical. It is slightly sunken and then enlarged to the whole fruit. The diseased part consists of small black spots and the obvious round pattern. Finally, the soft rot off or dry rot becomes stiff. Fruit, reduce yield and eggplant quality.
     Eggplant in the seedling stage, can spray the fungicide + tree general + plant cell immune factor strong immune function, induce interferon and active interleukin, inhibit residual virus replication, and promote plant positive energy ecological growth. Control the plant physiological diseases and invasive diseases by the host plant resistance mechanism and the principle of pathogenic toxicity variation. If the disease occurs after planting or after fruit setting, timely use of targeted drug + new high fat film for effective prevention and treatment.
