Abstract
The safe weedicide mainly formed from acetochlor, bensulfuron-methyl and adjuvant with the weight mixing ratio of 1-1.5 : 0.75-1 through a certain preparation process is safe for both rice in rice-transplating bed and seedling-throwing bed, and its efficiency for controlling various weeds can be up to 90%.
Description
The present invention relates to a kind of weed killer herbicide, be specially adapted to prevent and kill off the unifacial leaf and the broadleaf weed such as barnyard grass grass, nutgrass flatsedge, needle spikesedge herb, mexicana, Monochoria vaginalis, short arrowhead of paddy field.
Weeds in paddy field takes place all very serious in China rice district, in recent years, general along with the light cultivation technology, the expansion of Direct-seeding Rice, seedling throwing field, the straw chemical herbicide has become in the rice cropping distinct issues the most.Crop smothering is to loss, the harm of paddy rice, and light reached at 2-3 becomes, and is serious even more than 5 one-tenth.At present, the weed killer herbicide of killing weeds in rice field, mainly contain Bensulfuron-methyl, butachlor, the third careless amine, pyrazosulfuron, molinate etc., and some mixture preparations, but the weeding scope that these kinds have is narrower, can't once remove the grassy weed and the broadleaved herb in paddy field, the complex preparation that has prescription is unreasonable, causes poisoning easily.The application's a weeding of herbicide for paddy field energy, a season is effective.Safer to paddy rice simultaneously, be suitable for rice seedling throwing field management of weeds.Herbicidal effect can reach more than 90%.
The present invention's purpose is to provide a kind of composition ratio difference, but can effectively prevent and kill off the weed killer herbicide of paddy land weed.
The present invention is to be Main Ingredients and Appearance with Acetochlor and Bensulfuron-methyl, and interior filled and an amount of wetting agent, dispersant, high osmotic agent process.The part by weight of its Main Ingredients and Appearance Acetochlor, Bensulfuron-methyl is 1-1.5: 0.75-1.
The weed killer herbicide that makes by above-mentioned prescription compared with prior art, manufacturing conditions requires low, broad weed-killing spectrum, to rice safety, herbicidal effect is good.It is not only having good preventive effect to the transplant field weeds, also to seedling throwing field rice seedling safety, can reach more than 90% the weeds preventive effect simultaneously.
Be several groups of most preferred embodiment prescriptions part of the present invention below.
| Contain group component embodiment (%) | Acetochlor | Bensulfuron-methyl | Auxiliary agent |
| Embodiment 1 | ????8 | ????8 | ?84％ |
| Embodiment 2 | ???10 | ????6 | ?84％ |
| Embodiment 3 | ???13 | ???12 | ?75％ |
By above-mentioned most preferred embodiment recipe ingredient percentage, with Bensulfuron-methyl and auxiliary agent mixing---pulverize (fineness reaches 325 orders), add the abundant mixing of acetochlor oil then and get final product.
