Embodiment 1～12

[0041] Embodiment 1~12 wettable powder

[0042] Bacillus amyloliquefaciens, active ingredient B, dispersant, wetting agent, and filler are mixed, mixed uniformly in a mixing tank, pulverized by a jet mill and then mixed uniformly to produce the wettable powder product of the present invention. See Table 1 for details.

[0045]

Embodiment 13～20

[0046] Embodiment 13~20 water dispersible granules

[0047] Bacillus amyloliquefaciens, active ingredient B, dispersant, wetting agent, disintegrating agent, and filler are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain the preparation grain materials. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying. See Table 2 for details.

Embodiment 21～28

[0050] Embodiment 21~28 suspending agent

[0051] Dispersant, wetting agent, thickener (can be added or not), defoamer, antifreeze (can be added or not) are mixed evenly through high-speed shearing, and Bacillus amyloliquefaciens and active ingredient B are added, and deionized Make up the balance with water, and ball mill in a ball mill for 2 to 3 hours, so that the particle size of all the particles is below 5 μm, and the suspension product of the present invention is obtained. See Table 3 for details.

Abstract

The invention discloses a high-efficiency bactericidal composition containing bacillus amyloliquefaciens. The bactericidal composition comprises an active ingredient bacillus amyloliquefaciens and an active ingredient B, a weight range of the bacillus amyloliquefaciens is 0.2-70 billion spores per gram, and a weight range of the active ingredient B is 0.01-50%. The composition disclosed by the invention has high activity on multiple diseases of multiple crops, has an obvious synergistic effect, enlarges a bacteriocidal spectrum and has the characteristics of small dosage, rain wash resistance and obvious synergism.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency bactericidal composition containing Bacillus amyloliquefaciens to crop diseases. [0002] technical background [0003] Bacillus amyloliquefaciens (Bacillus amyloliquefaciens), the action mechanism of Bacillus amyloliquefaciens mainly includes secreting antibacterial substances, producing antagonism, competition between nutrition and space, inducing host resistance and promoting plant growth. [0004] In the actual process of agricultural production, the most likely problem in disease control is the emergence of disease resistance. Combination of ingredients from different varieties is a common method for controlling resistant diseases. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases, the compounding effects o...
