Problems solved by technology

Yet this bactericidal composition is compounded by three kinds of medicaments, and the stability of composition is not very good, and this has influenced the play of its composition medicine effect to a certain extent, therefore, although three kinds of medicaments are compounded than single medicament Shows synergy, but its efficacy still needs to be improved, and the cost needs to be further reduced

Embodiment 1

[0026] A suspending agent containing tributamol and chlorothalonil, in parts by weight, the raw material formula comprises tributamol 5%, chlorothalonil 15%, polycarboxylate 8%, lignosulfonate 4% and 68% %Deionized water.

[0027] The preparation method of the above-mentioned suspending agent is as follows: each raw material is added to the sand mill according to the formula, and after stirring evenly, it is pre-dispersed with a high shear machine, and then transferred to the sand mill for sand grinding, and the sand grinding medium zirconia beads are added to start. Sand grinding to make the particle size of 90% of the material below 3 μm, stop sand grinding after 5 hours, filter, and remove the zirconia beads to prepare a bactericidal composition suspension containing triconazole and chlorothalonil.

Embodiment 2

[0029] A suspending agent containing cyproconazole and chlorothalonil, the raw material formula comprises 5% cyproconazole, 15% chlorothalonil, 10% polycarboxylate, 5% lignosulfonate and 65% deionized Water, the preparation process of the suspending agent is the same as that in Example 1.

Embodiment 3

[0031] A suspending agent containing epoxiconazole and chlorothalonil, the raw material formula comprises 5% epoxiconazole, 15% chlorothalonil, 6% polycarboxylate, 8% lignosulfonate and 66% deionized water , the preparation process of the suspending agent is the same as that in Example 1.

Abstract

The invention relates to a bactericidal composite with triazole bactericide and chlorothalonil. The bactericidal composite mainly comprises the following raw materials by weight percent: 10%-30% of triazole bactericide, 10%-60% of chlorothalonil and 3%-15% of assistant, wherein the triazole bactericide is selected from one or more components of epoxiconazole, flutriafol, cyproconazole and penconazole; the assistant is formed by polycarboxylate dispersant and lignosulfonate wetting agent in a weight ratio of 1:0.15-3. When in use, good formulation stability can be maintained between the two active components of the bactericidal composite; and compared with the bactericide using a single component for controlling crop diseases, the range of the controlled diseases of the invention is expanded, the occurrence of resistance to drugs can be delayed, the drug effect is obviously increased, the drug dosage and frequency of administration per mu are reduced, the agricultural safety production is better ensured, and the ecological environment is protected.

Description

technical field [0001] The invention belongs to the field of pesticides, and particularly relates to a bactericidal composition. Background technique [0002] At present, fungicides can generally be divided into three categories according to their effect on diseases: [0003] 1. Protective fungicide: This type of fungicide can protect the application site that is not infected by germs and prevent the infection of germs. It needs to be sprayed before the crop is not exposed to disease or the disease occurs to receive the effect. Such as Bordeaux mixture, lime sulfur mixture, mancozeb, mancozeb, etc. [0004] 2. Eradication fungicides: These agents can directly kill the germs before the invasion and treat the infected application site, and are rarely used directly on crops. Such as the use of formalin to sterilize the infected seeds, fenugreek has the effect of eradicating wheat stripe rust and powdery mildew. [0005] 3. Therapeutic fungicides: These fungicides are also ca...
