There are many kinds of bean crops, mainly soybeans, broad beans, peas, mung beans, lentils, etc. The weeding of bean crops is different from wheat and corn. It is necessary to grasp the varieties and methods of medicine to achieve safe and efficient weeding. Here, Hui Nong.com edits several groups of formulas for the use of bean field weeding safe medicines. Let's take a look. There are two key periods in the control of weeds in bean fields: one is to treat the soil with pesticides during sowing, and the other is to spray the leaves of the bean crops at the seedling stage. It can also be called pre-emergence and post-emergence weeding. There are more than 60 common weeds in soybean fields. The most commonly used herbicides are: quizalofop, flufenacetate, methimazole nicotinic acid, acesulfame, bentazon, fluorocarboxylate. Grass ether, flufenacetate, and the like. Soybean integrated herbicide formula 1 Quinoxaline + acesulfame, formula characteristics: low cost, weed rebound, not control fragrant aconite; 2 Quinoxaline + flufenazone, formula characteristics: moderate cost, weeds are not easy to rebound, do not control fragrant aconite, suitable for southern planting areas; 3 quizalofop-ethyl and meidazole nicotinic acid, formula characteristics: high cost, no rebound of weeds, good effect of controlling 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 of fragrant 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 quizalophoprin + acifluorfen + bentazon, formulation characteristics: high cost, residual drug effect; 8 methimazole nicotinic acid + acetochlor, formula characteristics: high cost, no rebound of weeds, a wide range of use, can be used before and after seedlings, residual drug effect is easy to affect the crop. Soil treatment Commonly used herbicides are 50% acetochlor EC and 72% dulty cream (metolachlor); Acetochlor is a pre-emergence herbicide that is effective against weeds before germination and can only be used as a soil treatment agent. Applicable to crop corn, cotton, beans, peanuts, potatoes, etc. It can control the broadleaf weeds of annual grass weeds and some small seeds. It has special effects on annual grass weeds such as crabgrass, foxtail, goosegrass, valerian, thousand gold, maiden, wild oat, bluegrass, hard grass, and teff; Broadleaf weeds such as sorghum and Cuscuta also have certain control effects and are ineffective for perennial weeds. How to use (before seedlings) 1. Covering the mulch film: 80-100 ml of 50% acetochlor emulsifiable concentrate per mu before the film is applied, and 30 kg of water is sprayed on the flat surface or ridge surface, and then the film is coated and then the beans are planted. 2. Open field planting: After the beans are planted, level the ground, use 100-120 ml of 50% acetochlor emulsifiable concentrate per acre, spray 30 kg of water on the surface, and then mix the soil with scorpion. Stem and leaf treatment (post-emergence) (a) grass weeds 1. Use 20% of the 10% fine Kui Lingling emulsifiable concentrate per acre and spray evenly on 30 kg of water. 2. Use 10.8% of the high-efficiency grass cover per acre to 25-30 ml, and evenly spray 30 kg of water. (2) Broadleaf weeds 1. Use 48-180 ml of 48% bentazon water per acre and spray evenly on 30 kg of water. 2, 10% of the milk with 20% per acre, spray evenly on 30 kg of water. (3) Gramineae and broadleaf weeds 1. Use 10.8% of the high-efficiency grass emulsifiable concentrate 20-25 ml per mu to add 48-180 ml of 48% bentazon water, and spray evenly on 30 kg of water. 2, 10 to 50 ml per 10 mu of Jing Kui He Ling EC, add 48-180 ml of 48% bentazon water, spray evenly on 30 kg of water. Precautions Different bean crops have different drug resistance, so pay attention to safety when using. A small area test should be carried out before spraying to determine the dosage, weeding effect and safety, and then use it in a large area. Read the instructions for the use of the drug carefully before using the drug. Do not use the drug strictly according to the dosage. Do not increase the dosage to avoid phytotoxicity.
