Soybean corn field often grows a lot of weeds, which makes the farmers very entangled, so how can we get out of these weeds and make soybean corn seedlings harmless? Let’s take a look at how senior farmers can make their own way. Grass! 1. Common weeding formula for soybean and corn 1. There are more than 60 common weeds in soybean fields. The herbicides that are commonly used and have good efficacy are: quizalofop-p-ethyl, flufenacetate, methimazole nicotinic acid, acesulfame, bentazon, Carfenacetate, flufenacetate, and the like. 2. Soybean integrated herbicide formula 1. Quinoxaline + acesulfame, formula characteristics: low cost, weed rebound, no control of aconite; 2, quizalofop-ethyl + flufenacil, formula characteristics: moderate cost, weeds are not easy to rebound, do not control fragrant aconite, suitable for southern planting areas; 3, quizalofop-p-ethyl and methimazole nicotinic acid, formula characteristics: high cost, no rebound of weeds, good effect of controlling scented aconite, residual drug effect easily affects post-crop crops; 4, quizalophoprin + methimazole nicotinic acid + acesulfame, formula characteristics: high cost, no rebound of weeds, fast drug effect, good effect of control aconite, residual drug effect is easy to affect the post-crop crop; 5, quizalofop-ethyl + acifluorfen + acesulfame + bentazon, formulation characteristics: moderate cost, no residue; 6, quizalofop-ethyl + flufenazone + bentazon, the formulation characteristics are the same as 5; 7. Quinoxaline + acifluorfen + bentazon, formulation characteristics: high cost, residual drug effect; 8. Methimonic acid nicotinic acid + acetochlor, formula characteristics: high cost, no rebound of weeds, wide range of use, can be used before and after seedlings, residual drug effect is easy to affect the crop. Second, corn commonly used herbicide formula 1. There are more than 28 kinds of common weeds in corn fields. The herbicides with common price and good efficacy are: atrazine, nicosulfuron, mesotrione, etc., and can be formulated with vegetable oil additives. 2, corn comprehensive herbicide formula 1, atrazine + nicosulfuron, formula characteristics: low cost, slow effect (about 20 days), strong weed resistance, can control most weeds, anti-reed effect is not general; 2 atrazine + mesotrione, formula characteristics: the cost is slightly higher, quick effect (5-7 days), can prevent most weeds, the effect of preventing reeds in general. 3, atrazine + nicosulfuron + mesotrione, formula characteristics: high cost, wide range of use, quick effect (5-7 days), can prevent most weeds, also have better for reeds Control effect (used when reed 2-4 leaves). 4, Xiujin + oxazolone + vegetable oil additives, formula characteristics: high safety factor, does not affect the post-crop crops, control annual grass and broadleaf weeds good effect; use period: corn seedlings 2-4 leaf stage Or weed 2-5 leaf stage. 5, Xiujinjin + mesotrione + vegetable oil additives, formula characteristics: general safety factor, low temperature use has a slight impact on corn, does not affect the post-crop crops, control annual grass and broadleaf weeds good effect; use period : Maize seedlings 3-5 leaf stage or weed 2-5 leaf stage. 6, show to Tianjin + Nicosulfuron + vegetable oil additives or show to Tianjin + Nicosulfuron + bromoxynil + vegetable oil additives or formula characteristics: control annual grass and broadleaf weeds good effect, does not affect For crops, improper use can easily cause damage to corn; use period: 3-5 leaf stage of corn seedlings or 2-5 leaf stage of weeds. 7, nicosulfuron + oxazinone + vegetable oil additives or nicosulfuron + sulfonate sulfonate + show to Tianjin or nicosulfuron + sulfonate or oxacillin + nicosulfuron + show Jin + vegetable oil additives, formula characteristics: good control of grasses and broadleaf weeds, multi-age weeds need to be used before 6 leaves, does not affect the crops after the fall, improper use can easily cause corn damage; use period: corn Seedlings 3-4 leaf stage or weed 2-4 leaf stage. Third, simple homemade herbicide 1, homemade formula: white vinegar + salt + soap or detergent + hot water; These are commonly used items in the home, and the specific amount of raw materials can be used according to their own concentration. 2, the principle of formula: spray weeds at noon, white vinegar can quickly absorb the weed moisture, so that it is dried by the high temperature sun while dehydrating, salt can be alkalized by the surface soil, making weeds difficult to regenerate, detergent or The soapy liquid allows the self-made herbicide to adhere better to the weeds and enhance the herbicidal effect. The above is a complete introduction to the small method of homemade soybean cornfield herbicide formula. In daily life, not only soybeans, corn weeds, but also many weeds can be prepared by this method! Ningxia Eppen Biotec CO.,LTD , https://www.nxeppen.com
