[0038] (4) a preparation method of special herbicide for soybean field:
[0039] 1. Take 5% quizalofop-p-ethyl emulsifiable concentrate and add 48% bendazone water.
[0040] 2. Take 10% fluorfen fluoride EC, 5% quizalofop-p-ethyl EC and 48% bendazone liquid and mix them to get the wine spray liquid of the herbicide.
[0041] The important feature of the present invention is that bentazone will not cause phytotoxicity. The herbicidal spectrum is wide, not only effective on broad leaves such as cocklebur, but also effective on Cyperaceae such as goosegrass. But heavy use increases costs. Fluoxyfen kills weeds quickly, but if the dosage is large, soybeans will cause phytotoxicity. Both lowered the dose of the drug and bentazone, and then added the quizalofop-pyl that kills grasses. Expand the range of weeding and accelerate the speed of weeding. One-time spraying can ensure that soybeans are not harmed by weeds throughout the growth period.
[0042] The comparison test is s...
Embodiment 1
[0051] The components of soybean field special herbicide are:
[0052] 70 kg of 5% quizalofop-p-ethyl emulsifiable concentrate;
[0053] 120 kg of 48% bentazone aqueous solution;
[0054] 10% carboxyfen 15 kg;
[0055] First add 5% quizalofop-pyl-ethyl EC to 48% bendazone water, then take 10% acetoxyflufen EC and the above 5% quizalofop-pyl concentrate and 48% bendazone water and mix evenly, That is, the spray liquid of the herbicide is obtained.

Abstract
The invention discloses a herbicide for a bean field. The herbicide is characterized by comprising the following components in part by weight: 20 to 90 parts of 5 percent refined quizalofop missible oil; 20 to 150 parts of 48 percent aqueous bentazon and 5 to 30 parts of 10 percent fluoroglycofen-ethyl missible oil. A method for preparing the herbicide comprises the following steps of: adding the 5 percent refined quizalofop missible oil into the 48 percent aqueous bentazon; stirring and mixing the mixed solution; and mixing the 10 percent fluoroglycofen-ethyl missible oil with the two solutions to obtain the herbicide for the bean field. When the herbicide is sprayed in the bean field, a plurality of weeds can be killed at one time. The herbicide is safe and reliable, has a terminating rate of 99.4 percent, reduces the use amount of a single herbicide and reduces cost and labor intensity simultaneously. The herbicide for the bean field can enlarge a weed-killing spectrum, can radically kill a plurality of weeds quickly at one time, has no harmful effect on the bean field and after-cultured plants and is a harmless bean field post-emergency herbicide.
Description
technical field [0001] The invention relates to a chemical medicine for weeding and a preparation method thereof, in particular to a special herbicide for soybean fields and a preparation method thereof. Background technique [0002] There are many types of leguminous crops. There are many weeds mixed with it, the quantity is large, and the damage is serious. There are many grasses, sedges and broad-leaved weeds such as crabgrass, goosegrass, foxtail, barnyardgrass, cocklebur, cocklebur, iron amaranth, amaranth, and goosegrass, which become the weed advantage of legume crops population. [0003] Existing chemical herbicides for soybean fields are selective to weeds in soybean fields. The herbicides currently used in soybean fields are Doul, acetochlor and other pre-emergence herbicides; there are also post-emergence herbicides such as Gai Cao Neng, He Cao Ke, Wei Ba, Ke Kuo Le, Huwei, Bentasone, and Acetofen herbicide. If weed grass can effectively control the hazards o...
