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 kind of suspending agent containing fluconazole and chlorothalonil, by weight, its raw material formula comprises fluconazole 5%, chlorothalonil 15%, polycarboxylate 8%, lignosulfonate 4% and 68 %Deionized water.

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

Embodiment 2

[0029] A suspension containing cyproconazole and chlorothalonil, its raw material formula includes 5% cyproconazole, 15% chlorothalonil, 10% polycarboxylate, 5% lignosulfonate and 65% deionized Water, the preparation process of this suspending agent is with embodiment 1.

Embodiment 3

[0031] A suspension containing econazole and chlorothalonil, its raw material formula includes epoxiconazole 5%, chlorothalonil 15%, polycarboxylate 6%, lignosulfonate 8% and 66% deionized water , the preparation process of the suspending agent is the same as 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 productionis better ensured, and the ecological environment is protected.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a bactericidal composition. Background technique [0002] At present, fungicides can generally be divided into three categories according to their effects on diseases: [0003] 1. Protective fungicide: This kind of fungicide can protect the application site that is not infected by germs, and avoid the infection of germs. It needs to be sprayed before the crops are not exposed to the disease or before the disease occurs to receive the effect. Such as Bordeaux mixture, lime sulfur, mancozeb, zinc and so on. [0004] 2. Eradicative fungicides: This type of fungicide can directly kill the bacteria before invasion and treat the infected application site, and is rarely used directly on crops. If formalin is used to sterilize the infected seeds, Fenxining can eradicate wheat stripe rust and powdery mildew if used properly. [0005] 3. Therapeutic fungicides: These fungicides are also called...
