Problems solved by technology

Terbutin has a good effect on most annual dicotyledonous weeds, but there are certain disadvantages in actual use, such as unsatisfactory effect on monocotyledonous weeds
[0004] It can be seen from the above description that there are certain shortcomings that cannot be ignored in single-use drugs and single-dose. If a kind of dryland crop herbicide with better control effect and wider herbicidal spectrum can be developed

Embodiment 1

[0026] With 10 parts by weight of the active ingredient mixture (5 parts by weight of ametryn + 5 parts by weight of terbuthine), 10 parts by weight of the dispersant sodium polyacrylate, 8 parts by weight of the wetting agent fatty amide N-methyl Sodium sulfonate, 1 part by weight of disintegrating agent starch, 1 part by weight of disintegrating agent urea, 2 parts by weight of binder clay, 2 parts by weight of penetrating agent fatty alcohol polyoxyethylene ether, 6 parts by weight of carrier After the white carbon black and 60 parts by weight of carrier talcum powder are mixed evenly, they are ultrafinely pulverized into a 700-mesh fine powder with an airflow mill, and the resulting fine powder is kneaded by adding an appropriate amount of water in a kneader, and processed by a rotary granulator. Granules, dried at 50°C in a fluidized fluidized bed to obtain arazine-terbudine water-dispersible granules.

Embodiment 2

[0028] With the active ingredient mixture of 25 parts by weight (13.6 parts by weight of ametrazine+11.4 parts by weight of terbufen), 5 parts by weight of dispersant sodium dibutyl naphthalene sulfonate, 3 parts by weight of dispersant ethylene oxide - Propylene oxide block copolymer, 3 parts by weight of wetting agent alkylphenol polyoxyethylene ether, 3 parts by weight of wetting agent fatty alcohol polyoxyethylene ether sodium sulfate, 5 parts by weight of disintegrating agent sodium alginate , 1 part by weight of binder gelatin, 2 parts by weight of penetrant nonylphenol polyoxyethylene ether, 6 parts by weight of carrier glucose and 47 parts by weight of carrier ammonium sulfate, after mixing evenly, carry out ultrafine pulverization with a jet mill into 500-mesh fine powder, knead the resulting fine powder with appropriate amount of water in a kneader, granulate through a rotary granulator, and dry at 40°C in a fluidized fluidized bed to obtain aquarine-terbutyl water di...

Embodiment 3

[0030] With 40 parts by weight of the active ingredient mixture (24 parts by weight of ametrazine+16 parts by weight of terbufen), 5 parts by weight of dispersant sodium lignosulfonate, 5 parts by weight of wetting agent dodecylbenzenesulfonate Calcium acid calcium, 5 parts by weight of wetting agent sodium lauryl sulfate, 3 parts by weight of disintegrant urea, 2 parts by weight of disintegrating sodium nitrate, 3 parts by weight of binder dextrin, 1 part by weight of osmotic Sorbitan fatty acid ester polyoxyethylene ether, 6 parts by weight of carrier glucose and 30 parts by weight of carrier sucrose are evenly mixed, then ultrafinely pulverized into a 600-mesh fine powder with a jet mill, and the resulting fine powder is kneaded An appropriate amount of water is added into the container for kneading, granulated by a rotary granulator, and dried in a fluidized fluidized bed at 80°C to obtain arazine-terbudine water-dispersible granules.

Abstract

The invention discloses a herbicide composition containing ametryn and terbutryn and a preparation method thereof. The herbicide composition takes ametryn and terbutryn as active ingredients. The invention also discloses the preparation method of the herbicide composition. The composition disclosed by the invention consists of two active components and has low toxicity; and when the herbicide composition is used, the dosage of the ametryn can be reduced, the growth safety of crops can be ensured, the active components stay in crops and soil for such a short time that toxin accumulation is avoided, the dosage of the ametryn is lower than the normal dosage and grass can be killed effectively. In addition, the herbicide composition has a wider herbicide spectrum than terbutryn alone, monocotyledonous grass such as cockspur grass, hairy finger, green bristlegrass (green foxtail) and eleusine indica can be better killed, and at the same time, the respective drawbacks of ametryn and terbutryn which are used alone are overcome.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a herbicide and a preparation method thereof, and belongs to the technical field of pesticides. Background technique [0002] Amethyn, chemical name N-2-ethylamino-N-4-isopropylamino-6-methylthio-1,3,5-triazine, also known as amethyn. Ametryn is a selective systemic conductive herbicide with a rapid herbicidal effect. Its selectivity is related to the difference in plant ecology and biochemical reactions. It has the best control effect on newly germinated weeds and can be absorbed by 0-5 cm soil , forming a drug layer, so that the weeds will contact the chemical agent when they germinate out of the soil, and are used to control grass weeds and broad-leaved weeds in corn, sugarcane, pineapple, banana, citrus and other crop fields. There are certain disadvantages in the actual use of arazine, such as improper application time or excessive application amount, which wi...
