Embodiment 1

[0030] Embodiment 1: field test

[0031] In the Vegetable Base of Weifang University of Science and Technology in Shandong Province, the experimental tomato variety was Oubei, which was purchased from the US Sunnys (Beijing) Seed Company and planted on August 20, 2013.

[0032] The test established 3 treatments, respectively the traditional method 1 (abbreviated "pesticide simple spraying" method) of tomato stem disease control, method 2 (abbreviated "pesticide mixed spraying" method), the method of the present invention (abbreviated "pesticide mixed spraying" method) "Stem split dressing" method) and "soilless stem split dressing" method. 3 repetitions, arranged in random blocks, the area of ​​the plot is 36m 2 , 106 plants were planted in each plot, and the management measures were exactly the same. Select the plants infected with tomato bacterial pith necrosis in the initial stage of disease from each treatment, and its performance symptom is that the upper and middle lea...

Embodiment 2

[0057] Embodiment 2: field test

[0058] In the vegetable base of Weifang University of Science and Technology in Shandong Province, the experimental tomato variety was Qidali, which was purchased from Syngenta Seed Company and planted on February 15, 2014.

[0059] Three treatments were set up in the test, which were respectively the traditional method 1 of tomato stem disease control, method 2 and the method described in the present invention. 3 repetitions, arranged in random blocks, the area of ​​the plot is 36m 2 , 106 plants were planted in each plot, and the management measures were exactly the same. From each treatment, select the plants infected with tomato bacterial wilt in the initial stage of disease at the same time, and its performance symptoms are mainly 1 ~ 2 side branch leaves wilting, which can recover sooner or later; The tube bundles slowly turn dark brown.

[0060] Treatment 1: Select the susceptible tomato plants and healthy plants at the early stage of ...

Abstract

The invention belongs to the field of cultivation of vegetable crops, and particularly relates to a composition for preventing and treating diseases of stem parts of tomatoes. The composition contains copper hydroxide wettable powder and mud at a mass ratio of 1 to (15-35). The composition is prepared by the following steps: mixing the copper hydroxide wettable powder with the mud evenly, adding water and stirring into insecticide mud; splitting the lesion parts of the stems, and scraping off the lesion tissues; and smearing the insecticide mud on the lesion parts of the stems. The medication frequency is reduced; relatively good prevention and treatment effects on the infected plant can be achieved by one medication; and the insecticide amount is reduced. Smearing medication is carried out by preparing the insecticide mud, so that the types of medication and the medication amount are greatly reduced; the medication amount is only 20%-30% of that of a traditional method, so that the working efficiency can be obviously improved; the production cost is reduced; time and labor are saved; meanwhile, the pollution to the crops and the environment are reduced; pesticide residues sprayed on the fruits are greatly reduced; the disease resistance on the pesticide is effectively delayed; the diseases of the stems can be effectively prevented; and large-area prevalence of the diseases is reduced, so that high and stable yield is achieved.

Description

technical field [0001] The invention belongs to the field of cultivation of vegetable crops, in particular to a composition for preventing and controlling tomato stem diseases, and also relates to the application of the composition for preventing and controlling tomato stem diseases. Background technique [0002] As a major vegetable, the planting area of ​​tomato in the whole country is increasing continuously. The diversification of its planting methods and the increase of the field multiple cropping index have led to a significant increase in the types and area of ​​stem diseases. The damage is becoming more and more serious, and the difficulty of control is gradually increasing. Become a serious obstacle restricting tomato production. [0003] At present, for the prevention and control of tomato stem diseases, conventional spraying of chemical agents is still the main method. This method requires a large amount of pesticides and requires comprehensive spraying of tomato ...
