Embodiment 1

[0027] A kind of suspending agent containing epoxiconazole and azoxystrobin, by weight, its raw material formula comprises epoxiconazole 10%, azoxystrobin 10%, polycarboxylate 8%, lignosulfonate 2% and 70% deionized water.

[0028] 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 95% of the material below 3 μm, stop the sand milling after 5 hours, filter, remove the zirconia beads, and promptly prepare the suspension containing epoxiconazole and azoxystrobin.

Embodiment 2

[0030] A suspension containing penconazole and azoxystrobin, its raw material formula includes penconazole 10%, azoxystrobin 10%, polycarboxylate 2%, lignosulfonate 6% and 72% deionized water , the preparation process of the suspending agent is the same as in Example 1.

Embodiment 3

[0032] A suspension containing cyproconazole and azoxystrobin, its raw material formula includes epoxiconazole 10%, azoxystrobin 10%, polycarboxylate 5%, lignosulfonate 5% and 70% deionized water , the preparation process of the suspending agent is the same as in Example 1.

Abstract

The invention relates to a suspending agent type and water dispersible granule type sterilization compound which comprises the following raw materials in percentage by weight: 5-50% of triazole fungicide, 5-50 % of azoxystrobin and 3-15 % of accessory ingredient, wherein the triazole fungicide is one or the combination selected from Epoxiconazole, lutriafol, Cyproconazole and Penconazole, and theaccessory ingredient is composed of polycarboxylate dispersing agent and lignosulfonate wetting agent at the weight ratio of 0.15-6:1. The sterilization compound of the invention keeps good compound stability for two active ingredients in use; compared with the condition that single solvent is used for preventing and curing crop diseases, the sterilization compound enlarges disease prevention andcure range, delays the generation of resistance to drugs, obviously improves pesticide effect, reduces dosage and application times for each acre, preferably ensures the safe production of agriculture and protects ecological environment.

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...
