Embodiment 1

[0032] Example 1 (60% pyraclostrobin·diphenhydrine suspension concentrate)

[0033] Raw material formula: by mass percentage

[0034]

[0035] The preparation method is as follows:

[0036] According to the formula, weigh each component in proportion, put it into a ball mill and mill it for 30 minutes, filter, pump it into the dispersion tank for 3 minutes at high speed and then grind it fully with a sand mill to control the particle diameter of the solid component within 2 microns, and the grinding is completed Finally, stir evenly to obtain the suspension concentrate product.

Embodiment 2

[0037] Embodiment 2 (preparation method of 30% pyraclostrobin · diphenhydrine suspension concentrate)

[0038]

[0039]

[0040] Preparation method: same as Example 1.

Embodiment 3

[0041] Embodiment 3 (preparation method of 40% pyraclostrobin · diphenhydrine suspension concentrate)

[0042]

[0043] Preparation method: same as Example 1.

Abstract

The invention discloses a bactericidal composition containing pyraclostrobin and hydantoin. The bactericidal composition comprises active components of pyraclostrobin and hydantoin in the weight ratio of 1:20-20:1, and the active components account for 5-60 wt.% of the composition. The bactericidal composition provided by the invention has high bactericidal activity, delays the emergence and development of pathogen resistance, reduces the dosage of prevention in actual production, and has the advantages of economical performance, high efficiency, safety and environment-friendliness. The bactericidal composition has especially substantial control effect on grape gray mold and Alternaria kikuchiana Tanaka.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicidal composition containing pyraclostrobin and dihydantoin and application thereof. Background technique [0002] Botrytis cinerea is a common and difficult to control fungal disease of crops in open fields and protected areas. It is a low-temperature and high-humidity disease. The growth temperature of the pathogen is 20-30°C. period of high incidence of disease. Botrytis cinerea is caused by the infection of Botrytis cinerea, which is a fungal disease and can affect flowers, fruits, leaves and stems. Botrytis cinerea diseased seedlings are light in color, and the leaves and petioles are off-white, water-soaked, and the tissues soften to rot. Botrytis cinerea grows on the surface when the humidity is high. The young stems mostly have irregular water-soaked spots at the base of the petiole, which quickly become soft and rotten, constricted or folded down, and fina...
