Problems solved by technology

Although these methods have achieved a certain control effect, because the disease occurs and develops in the tomato pith, the control rate of conventional spraying, root irrigation and injection is very low, usually less than 50%, and it will still cause serious losses.

Embodiment 1

[0016] Example 1, in a certain tomato greenhouse in Shouguang City, Shandong Province, the planting variety is Qidali. When bacterial pulpal necrosis is found in the field, the control part 1 is sprayed with 1000 times of 20% thiabactin copper suspension plus 1000 times of 47% Garenon wettable powder, and 10 days later with the same concentration of the above mixed medicine. Spray 1 time; Control 2 part with Zhongshengmycin 1000 times solution plus 40% agricultural streptomycin 2000 times solution for root irrigation, 250 grams per plant irrigation solution; Control 3 part DT500 times solution plus rosinic acid copper 600 times solution , inject with a syringe from the upper part of the diseased part; in the test part, cut the diseased part of the plant with a knife, and the depth of the incision varies according to the actual situation, usually 1 / 2-2 / 3 of the stem thickness of the diseased part of the tomato plant , clear the bacterial concentration, and smear the incision si...

Abstract

The invention discloses a method for controlling tomato bacterial medullary necrotic disease. The method comprises the following steps of: cutting a notch at the nosogenic part of a tomato plant; clearing bacterial ooze; and applying mixed liquor of forchior fennron and systemic antibiotic on the notch part, wherein the depth of the notch is 1 / 2-2 / 3 of the stem of the nosogenic part of the tomato plant, the concentration of forchior fennron is 10-15 mg / kg, and the concentration of antibiotic is 750-1000 mg / kg. The tomato bacterial medullary necrotic disease can be thoroughly cured, and the yield of tomato is improved.

Description

technical field [0001] The invention relates to a method for preventing and treating bacterial pith necrosis of tomato, belonging to the technical field of agriculture. Background technique [0002] Bacterial pith necrosis is an important disease of tomato, which occurs all over the country. When the damage is serious, it will have a great impact on tomatoes and cause huge losses to vegetable production. The main symptoms of the disease: leaves of early onset plants are yellow and withered, and leaves of late onset plants are withered; dark brown lesions are mostly on the lower part of the stem, and can also occur on the middle part of the stem or branches, and finally the whole plant dies. In the early stage of the disease, the young leaves are chlorotic, the upper part of the severely affected plants is chlorotic and wilting, the stem is necrotic, and brown to dark brown spots appear on the surface of the diseased stem, and the outside becomes hard. Longitudinal dissecti...
