Embodiment 1

[0020] Example 1 : 60% boscalid · mancozeb wettable powder.

[0021] Boscalid 30%, mancozeb 30%, sodium lauryl sulfate (surfactant) 2.5%, white carbon black (filler) 4%, sodium lignosulfonate (dispersant) 5.5%, Bentonite (filler) makes up to 100%. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 60% boscalid·mancozeb wettable powder.

[0022] The above-mentioned 60% boscalid-mancozeb wettable powder was used to control botrytis cinerea, diluted with water to 800 times liquid and sprayed evenly at the early stage of the disease, and the control effect was 87.5% after 3 days of application. Using 80% mancozeb wettable powder 600 times liquid and 50% boscalid water dispersible granule 500 times liquid as control agents, the same method was used to apply the pesticides, and the 3d control effects were 76.2% and 82.7% respectively. The test showed that 60% boscalid·mancozeb wettable powder had a good con...

Embodiment 2

[0023] Example 2 : 70% boscalid·mancozeb water dispersible granules.

[0024] Boscalid 20%, mancozeb 50%, calcium dodecylsulfonate 7% (wetting agent), lignosulfonate (dispersant) 4%, urea (disintegrant) 2%, Polyethylene glycol (binder) 3%, gum arabic (stabilizer) 3%, kaolin to make up to 100%. Dry pulverize, granulate, dry and sieve the above formula in proportion to obtain 70% boscalid·mancozeb water dispersible granules.

[0025] The above-mentioned 70% boscalid·mancozeb water dispersible granule was used to prevent and control cucumber gray mold. In the early stage of the disease, it was diluted with water to 1000 times and sprayed evenly. The control effect was 90.7% after 3 days of application. Using 80% mancozeb wettable powder 600 times liquid and 50% boscalid water dispersible granule 500 times liquid as control agents, the same method was used to apply the pesticides, and the 3d control effects were 72.4% and 86.8% respectively. The test showed that 70% boscalid·m...

Abstract

The invention discloses a bactericidal composition of boscalid and mancozeb. The effective component of the bactericidal composition is composed of boscalid and mancozeb with a mass part ratio of 1:3-5:1. The bactericidal composition provided by the invention is suitable to be used for controlling vegetable gray mold. The bactericidal composition provided by the invention has a substantial synergetic effect, and assists in reducing pesticide dose. When the bactericidal composition is popularized, great economic and social effects are provided.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a bactericidal composition of boscalid and mancozeb, which is used for preventing and treating vegetable gray mold. Background technique [0002] Botrytis cinerea is an important and common disease in the vegetable planting process. It is a fungal disease that is common and difficult to control in open field and protected crops. It is a low-temperature and high-humidity disease. ℃, when the temperature is 20-25 ℃, and the humidity is continuously above 90%, it is the period of high incidence of diseases. Botrytis cinerea is caused by the infection of Botrytis cinerea, which is a fungal disease and can affect flowers, fruits, leaves and stems. The fruit is infected, and the green fruit is severely damaged. The remaining stigmas or petals are mostly infected first, and then expand to the fruit, resulting in a grayish white peel with a thick gray mold layer, which is water rot...
