Abstract
The present invention is the compound herbicide that a kind of novel paddy field is used, belong to a kind of composite pesticide, the domestic and international at present compound herbicide of producing, still the compound herbicide that does not have a kind of paddy field, the present invention has invented the compound herbicide that a kind of novel paddy field is used, and has two kinds of formulations of missible oil and granule, it is wide to have herbicidal spectrum, cost is low, and the lasting period is long, characteristics of high efficiency and low toxicity.Good through inner trial effect, reach about 85-100% for several main weeds control efficiency such as straw, Monochoria vaginalis, wild arrowhead, fescue, pondweeds.
Description
The present invention is the compound herbicide that a kind of novel paddy field is used, and belongs to a kind of composite pesticide.
The domestic and international at present compound herbicide of producing, still the compound herbicide that does not have a kind of paddy field, still use some unicity weed killer herbicides such as nitrofen, butachlor, the big shape of standing grain in the paddy field, make that some broad-leaved type weeds and the stem or leaf of cattail are out of hand in the paddy field, this class weed encroachment is serious, becomes the big problem on the current Rice Production.
The present invention is directed to the problems referred to above and invented the compound herbicide that a kind of novel paddy field is used, according to China paddy land weed group, select butachlor to straw, symetryne to pondweed, mcpa sodium to the stem or leaf of cattail and the specific characteristics of broadleaved herb.Select for use butachlor, symetryne, mcpa sodium, dimethylbenzene, delachlor emulsifier, bentonite clay particle (containing bentonite 58%, calcium carbonate 32%, alkylbenzene sodium phosphate 2%, tertiary sodium phosphate 4%, xylonic acid sodium 4%) to make rice field emulsion for cleaning, the clean granule in rice field, one rice field emulsion for cleaning, total effective content is 40～65%.Wherein each component content is that butachlor 27～43.3%, symetryne 8.4～14%, mcpa sodium 4.6～7.7%, dimethylbenzene 38.3～1.7%, delachlor emulsifier 21.7～33.3%, its two rice fields total effective content of clean granule are 3～8%, wherein each component content is: butachlor 2～5.3%, symetryne 0.65～1.7%, mcpa sodium 0.35～1%, dimethylbenzene 2%, delachlor emulsifier 1.5～4.2%, bentonite clay particle 93.5～85.8%.
The present invention compare with " killing red S " have broad weed-killing spectrum, advantage that cost is low, with standing grain field net phase ratio, it is close or slightly high to kill careless effect, but cost is clean lower by 30～40% than standing grain field, and the clean raw material in rice field is based on domesticly, uses the clean weeding in rice field, the per hectare effective dose is 1.5～1.8Kg, the present invention is good through inner experiment effect, and it is long that the present invention also has the lasting period, the advantage of high-efficiency low-toxicity.Reach about 85～100% for several main weeds control efficiency such as straw, Monochoria vaginalis, wild arrowhead, fescue, pondweeds.
Claims (3)
1, the compound herbicide (rice field is clean) used of the said a kind of novel paddy field of the present invention is characterized in that: missible oil or the granule made by butachlor, symetryne, mcpa sodium, dimethylbenzene, delachlor emulsifier and bentonite clay particle etc.
2, the said rice field of claim 1 is clean, and total effective content is 40～65%, and wherein each component content is a butachlor 27～43.3%, symetryne 8.4～14%, mcpa sodium 4.6～7.7%, dimethylbenzene 38.3～1.7%, delachlor emulsifier 21.7～33.3%.
3, the clean granule in the said rice field of claim 1, total effective content be 3～8% wherein each component content be: butachlor 2～5.3%, symetryne 0.65～1.7%, mcpa sodium 0.35～1%, dimethylbenzene 2%, delachlor emulsifier 1.5～4.2%, bentonite clay particle 93.5～85.8%.
