Embodiment 1

[0043] The paddy field compound herbicide provided in this example is a wettable powder (WP), which is mainly made of the following raw materials: 7% pyrimifluben, 1.5% pyrifluconate, lignosulfonic acid 6% of salt, 2% of calcium dodecylbenzenesulfonate, 1.5% of carboxymethyl cellulose and 82% of filler, the filler is a mixture of 2% of white carbon black and 80% of kaolin. Wherein, lignosulfonate is used as a dispersant, calcium dodecylbenzenesulfonate is used as a wetting agent, and carboxymethyl cellulose is used as a binder.

[0044] The paddy field compound herbicide provided in this example is prepared by the following process: first add half of the filler into the mixer, add the weighed dipacenil and pyrimethanil, and mix evenly, and then add the lignin Sulfonate, calcium dodecylbenzenesulfonate, carboxymethyl cellulose and the remaining fillers are added together, mixed evenly to obtain a mixture, and then crushed by airflow until 99% of the mixture can pass through a 3...

Embodiment 2

[0050] The paddy field compound herbicide provided in this example is a large-grained paddy field compound herbicide, which is mainly made of the following raw materials: 12% of fenpyrafen, 0.8% of mesotrione, and 8% of lignosulfonate , Sodium dodecylbenzene sulfonate 3%, 500# agricultural milk 3%, porous perlite 73.2%. Among them, lignosulfonate is used as a dispersant, calcium dodecylbenzenesulfonate is used as a wetting agent, and porous perlite is used as an adsorbent.

[0051] The paddy field compound herbicide provided in this example is formulated through the following process: mixing dipacenil, mesotrione, lignin sulfonate, calcium dodecylbenzene sulfonate and 500# agricultural milk together uniform, then add the prepared porous perlite, mix to obtain a mixed material, transfer the mixed material to a kneader for kneading, extrude and granulate through an extrusion granulator, and then use a fluidized bed to dry, granulate, After sieving, the large-grain finished prod...

Embodiment 3

[0057] The paddy field composite herbicide provided by the present embodiment is a microemulsion (ME), which is mainly made of the following raw materials: bisacenil 9%, trifentrazone 9%, styrene ( Methyl styrene) phenol polyoxyethylene polyoxypropylene ether 6%, styrene ethylphenol polyoxyethylene ether 8%, cyclohexanone 6%, n-butanol 4%, water 58%. Wherein, styrene (methylstyrene) phenol polyoxyethylene polyoxypropylene ether and styrene ethylphenol polyoxyethylene ether are used as emulsifiers, and cyclohexanone, n-butanol and water are used as solvents.

[0058] The paddy field compound herbicide provided in this example is formulated by the following process: after mixing bisacenil and flumezone-sulam, dissolve in a solvent composed of cyclohexanone and n-butanol, and then add styrene (Methylstyrene) phenol polyoxyethylene polyoxypropylene ether and styrene ethylphenol polyoxyethylene ether, mix evenly, stir and slowly pour into water at the same time, after W / O phase inv...

Abstract

The invention provides a compound rice field herbicide, and relates to the technical field of pesticides. The compound rice field herbicide is mainly prepared from 0.05%-49.7% of pyraclonil, 0.3%-49% of a herbicide and the balance auxiliary materials, wherein the herbicide is selected from one or more of pyriminobac-methyl, mesotrione, triafamone, propyrisulfuron, dichloroquinoline oxadiazon and cyhalofop-butyl. The compound rice field herbicide has the good weeding effect, is long in durable period and can effectively reduce harm to the environment.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound herbicide for paddy fields. Background technique [0002] The direct seeding field is to soak the rice seeds for 2 to 3 days to germinate, and then throw them directly to the rice field. First put it on the seedling bed in the seedling room to germinate, and then use a seedling throwing machine or manually throw it into the rice field after 20 to 30 days. Convenient, suitable for machine harvesting; transplanting field is to put the rice seeds in the container of the seedling room or the seedling bed to germinate, and then sow them in the seedling field, and then transplant the rice into the rice field after about 30 to 40 days. The rice has the advantages of strong lodging resistance, strong resistance to diseases and insect pests, and is convenient for manual harvesting. Statistical data show that: without using herbicides, the impact on the yield of the direct ...
