Problems solved by technology

Some agricultural measures, such as crop rotation, deep furrows and narrow borders, rational fertilization, and field cleaning, all have a certain effect on reducing diseases, but they cannot fundamentally control diseases, and disease-resistant breeding also has certain difficulties
Traditional chemical control methods not only have high costs, heavy pollution, and damage to soil ecology, but also cause excessive residues of harmful substances

Embodiment 1

[0018] In 2011, in Luwo Village, Xishan Township, Xifeng County (altitude 910m) and Jianxin Village, Farm Town, Xiuwen County (altitude 1270m), where the terrain is flat, the fields are neat, irrigation and drainage are convenient, the soil is loose, and the fertility is moderate, which is suitable for tomato planting requirements. , respectively adopted the method of the present invention to handle 100 strains of Hongzera 118, the soil in the two places of the above test is a tidal mud field, and bacterial wilt has occurred seriously over the years, and the specific treatment methods are as follows:

[0019] (1) Measure 45ml of microbial agent Xianfeng 168, and dilute the measured Xianfeng 168 and water at a ratio of 1:100 to make Xianfeng 168 liquid medicine. Soak the tomato seeds with Xianfeng 168 medicinal solution for 2 hours, then broadcast, cover with shallow soil, and cover with black omentum. Before the tomato seedlings were transplanted, the tomato seedlings were soa...

Embodiment 2

[0032] On the basis of the experiment in 2011, in 2012, in Xifeng County and Xiuwen County, where the soil is tidal muddy field, the soil texture is loose, the permeability is good, and the fertility is good. Field efficacy screening test". Plant 4 rows of tomatoes in each plot, 30 plants in each row, a total of 120 plants; the distance between rows is 0.56m, the distance between plants is 0.65m, and the half growth period is covered with film. Adopt this method to wherein 120 tomato plants have been processed, and concrete processing method is as follows:

[0033] (1) Measure 20ml of Xianfeng 168, and dilute the measured Xianfeng 168 with water at a ratio of 1:200 to make Xianfeng 168 liquid medicine. Soak the tomato seeds with Xianfeng 168 medicinal solution for 2 hours, then broadcast, cover with shallow soil, and cover with black omentum. Before the tomato seedlings were transplanted, the tomato seedlings were soaked with Xianfeng 168 medicinal solution for 30 minutes, a...

Embodiment 3

[0047] On the basis of the tests in 2011 and 2012, in 2013 in the tomato planting area in Example 1 and Example 2, the "Field Drug Efficacy Re-test of Controlling Tomato Bacterial Wilt" was carried out on Hongzela 118. Plant 4 rows in each plot, 40 plants in each row, and 90 tomato plants; the row spacing is 0.56m, the plant spacing is 0.65m, and the half growth period is covered with film. Using the method described in the present invention and the following drug treatment methods, 150 tomato plants were respectively treated, and the relative control effect of the medicine was calculated using the water treatment as a control.

[0048] Processing method described in the present invention is as follows:

[0049] (1) Measure 15ml of Xianfeng 168, dilute the measured Xianfeng 168 and water at a ratio of 1:300 to make Xianfeng 168 medicinal solution, then soak tomato seeds with Xianfeng 168 medicinal solution for 2 hours, Sow, cover with shallow soil, and cover with black omentu...

Abstract

The invention discloses a method of preventing tomato bacterial wilt. The method comprises the steps of preparing xianfeng 168 liquid medicine by diluting microbial pesticide-xianfeng 168 and water according to a 1 to (100-300) weight ratio, and then carrying out routine seeding after soaking tomato seeds for 2 hours by adopting the prepared xianfeng 168 liquid medicine; soaking tomato seedlings for 30 mins by adopting the xianfeng 168 liquid medicine again before transplanting the tomato seedlings; preparing zhongshengmycin liquid medicine by zhongshengmycin and water according to a 1 to (800-1200) weight ratio 7 days after the tomato seedlings are planted, carrying out root irrigation on the tomato seedlings by adopting the prepared zhongshengmycin liquid medicine, wherein 100 to 200 ml of zhongshengmycin liquid medicine is poured in the roots of each tomato seedling. By adopting the method of preventing the tomato bacterial wilt, disclosed by the invention, a good effect of preventing the tomato bacterial wilt is obtained, the incidence rate of the tomato bacterial wilt can be obviously reduced, the survival rate of tomato plants is ensured, and the quality of tomatoes is increased; the operation is simple, convenient and easy to master, and the labor cost is saved; the method has no negative effects on the environment and is suitable for large-area promotion.

Description

technical field [0001] The invention relates to a method for preventing and treating tomato bacterial wilt, belonging to the technical field of plant disease prevention and control. Background technique [0002] Tomato bacterial wilt is a bacterial disease caused by the infection of Pseudomonas solanacearum Smith. It has a wide distribution and is common in tropical and subtropical regions. It often causes devastating disasters and seriously affects tomato production. In my country, tomato bacterial wilt has always been one of the main diseases affecting tomato production, and tomato scientific and technological workers have been devoting themselves to research on the control of tomato bacterial wilt. Some agricultural measures, such as crop rotation, deep furrows and narrow borders, rational fertilization, and field cleaning, all have certain effects in reducing diseases, but they cannot fundamentally control diseases, and disease-resistant breeding also has certain difficu...
