Embodiment 1

[0175] Example 1 Redispersion of Boscalid and Kresoxim-methyl Abrasives

[0176] Stability scheme: at 38 o C, store the grind described in Section 1.2 in 2 oz bottles for 6 weeks. Assesses the ability of the precipitate to redisperse, based on the time required to homogenize the sample by shaking at a moderate speed. The shorter time required to redisperse the precipitate is ideal. Vibrating the bottle horizontally and moving it forward and backward is considered a complete vibration. Moderate vibrations are about two full vibrations per second. The sediment must be completely redispersed, free of any sediment at the bottom of the bottle, and no clumps or agglomerates in bulk samples.

[0179] Sample 1-1 represents the abrasive described in Section 1.2 with an average particle size of 0.8-1.3 microns. Samples 1-2 represent millbases of similar composition, but containing larger particles.

Embodiment 2

[0187] Example 2 Dilution performance of final product

[0188] Dilution scheme: Using the typical dosage, dilute the final product formulation as described in 1.3 and 2.3 in water with a hardness of 50ppm and 1000ppm. Samples were diluted in 100ml graduated cylinders for a total volume of 100ml (formulation plus water). The sample was then subjected to 10 complete inversions to thoroughly mix the sample. Let the graduated cylinder stand at room temperature for 24 hours. After 24 hours, record the number of inversions to completely redisperse the pellet. Fewer inversions are required to completely redisperse the pellet indicating improved redispersibility of the final product.

[0189] Sample 3-1 represents the final product described in Section 1.3 with an average particle size of 0.8-1.3 microns. Sample 3-2 represents a final product with a similar composition but containing a larger particle grind.

Abstract

The invention relates to a boscalid and kresoxim-methyl-contained suspending agent or suspoemulsion. The boscalid and kresoxim-methyl-contained suspending agent comprises boscalid, kresoxim-methyl and a dispersing agent agriculturally acceptable, wherein the average grain diameter of bactericidal effective dose of the boscalid and kresoxim-methyl is 0.8-1.3 micron. The invention further includes a boscalid and kresoxim-methyl-contained suspoemulsion which comprises boscalid, kresoxim-methyl and the dispersing agent agriculturally acceptable, and the average grain diameter of bactericidal effective dose of the boscalid and kresoxim-methyl is 0.8-1.3 micron. According to the invention, compared with a water system similarly prepared and containing boscalid and kresoxim-methyl-contained suspending agent and suspoemulsion, wherein the average grain diameter of bactericidal effective dose of the boscalid and kresoxim-methyl is greater than 0.8-1.3 micron, the water system containing boscalid and kresoxim-methyl-contained suspending agent and suspoemulsion, disclosed by the invention, with the average grain diameter of bactericidal effective dose of the boscalid and kresoxim-methyl of being 0.8-1.3 micron, remarkably improves stability and efficacy of physical storage.

Description

technical field [0001] The invention relates to a suspension or suspoemulsion containing boscalid and kresoxim-methyl. Background technique [0002] Boscalid, its chemical name is 2-chloro-N-(4'-chlorodiphenyl-2-yl)nicotinamide, and its structural formula is: [0003] [0004] Boscalid is a nicotinamide fungicide, which was first successfully developed by BASF in Germany. It has a wide bactericidal spectrum and has a preventive effect. It is active against almost all types of fungal diseases. It is effective in preventing and controlling powdery mildew, gray mold, Root rot, sclerotinia, and various rot diseases are very effective, and it is not easy to produce cross-resistance. It is also effective for resistant bacteria to other chemicals. It is mainly used for the prevention and control of diseases including rapeseed, grapes, fruit trees, vegetables, and field crops. . The test results show that boscalid has obvious control effect on Sclerotinia sclerotiorum, and the ...
