Embodiment 1

[0029] Example 1 Indoor bacteriostatic test of mefenaxyl and propamocarb hydrochloride in different proportions on grape downy mildew

[0030] Table 1 Indoor antibacterial test results of mefenaxyl and propamocarb hydrochloride in different proportions against grape downy mildew

[0031]

[0032] It can be seen from Table 1 that when the ratio of mefenaxyl and propamocarb hydrochloride is 1:5, the indoor bacteriostatic effect on grape downy mildew is the best, and the bacteriostatic rate reaches 98.26%, which is obviously better than other ratios.

Embodiment 2

[0033] Example 2 6% metalaxyl-propamocarb hydrochloride aqueous solution

[0034] According to the following weight ratio:

[0035] Nailaxyl 1%;

[0036] Propamocarb hydrochloride 5%;

[0037] Thymol 5%;

[0038] Alkylphenol polyoxyethylene ether 10%;

[0039] Calcium dodecylbenzenesulfonate 2%;

[0040] Triphenylphosphite 0.5%;

[0041] Organosiloxane 0.1%;

[0042] Water up to 100%.

[0043] The preparation method of the water agent in Example 2 is: the above-mentioned components are weighed according to the weight percentage in advance for future use, and the water is first put into the reactor at room temperature, and the mixer of the reactor is turned on, and the metalaxyl fine is added under the stirring condition. After the propamocarb hydrochloride is completely dissolved, after putting in the surfactant, stop feeding, close the pumping valve, open the vent valve of the reaction kettle, add synergist and stabilizer respectively, and continue stirring for 30 minu...

Embodiment 318

[0052] Example 3 18% 18% metalaxyl-propamocarb hydrochloride aqueous solution

[0053] According to the following weight ratio:

[0054] Nailaxyl 3%;

[0055] Propamocarb hydrochloride 15%;

[0056] Thymol 5%;

[0057] Renylphenol polyoxyethylene ether 12%;

[0058] Calcium dodecylbenzenesulfonate 2%;

[0059] Triphenylphosphite 0.5%;

[0060] Organosiloxane 0.1%;

[0061] Water up to 100%.

Abstract

The invention discloses a metalaxyl-M and propamocarb hydrochloride compounded aqueous solution and an application thereof. The metalaxyl-M and propamocarb hydrochloride compounded aqueous solution is prepared from, by weight, 1-20% of metalaxyl-M, 1-60% of propamocarb hydrochloride, 3-30% of thymol, 5-20% of a surface active agent, 0.1-2% of stabilizer, 0.1-0.3% of defoamer and the balance of water. The metalaxyl-M and propamocarb hydrochloride compounded aqueous solution is efficient, safe and environment friendly, synergistic effect on the component is achieved, crop output can be increased, quality of fruit is improved, cost is lowered and generation of drug resistance to bacteria is beneficially suspended; the metalaxyl-M and propamocarb hydrochloride compounded aqueous solution can be used for preventing and controlling crop diseases of citrus burning disease, corynespora cassiicola, pepper phytophthora blight, rice seedling blight and rice blast, plasmopara viticola and the like.

Description

technical field [0001] The invention relates to an agricultural fungicide, specifically an aqueous formulation containing metalaxyl, propamocarb hydrochloride and thymol and its application. [0002] technical background [0003] Metalaxyl is an amide fungicide with protective and therapeutic effects. It can be absorbed by the roots, stems and leaves of plants, and then transported to the various organs of plants along with the water transport in the body. It has better control effect on vegetables, fruit trees, tobacco, oilseeds, cotton, grain and other crop diseases caused by Downy Mildew, Phytophthora, and Pythium. [0004] Propamocarb hydrochloride is a carbamate fungicide, which is safe and efficient, and has special effects on oomycetes. It mainly inhibits the biosynthesis of phospholipids and fatty acids in the cell membrane of pathogens, and inhibits the growth of mycelium, the formation and germination of sporangia. It has good systemic conductivity. When used as so...
