Soybeans will not be harmed by the rain after a few days of spraying

After soybean spraying, it is generally not necessary to re-spray it in case of rain 6 hours after spraying. However, if there is heavy to heavy rain within 6 hours after spraying, it is necessary to spray in time after the rain stops, but the concentration needs to be appropriately reduced to avoid pesticide damage.

Please note that the duration of the effect may vary from region to region and weather conditions, so please judge on a case-by-case basis.

Soybean post-emergence herbicides are: quinoxalin, steady killing, Napjing, Kekole (pay attention to the dosage), etc., mainly used for foliar spray, after a soybean growth period, there is no pesticide damage, after soybean harvest, the next stubble and then plant corn, will not cause harm at all.

In addition to the pesticides mentioned on the second floor above, there are herbicides in soybean fields, chlorsulfuron (commonly known as "beansulfuron"), and micao tobacco (trade names: Pusit, Beangrass, Bean Xerox, Bean hoe, Golden pear, etc. Both pesticides (dasulfuron, mixanta, mimegran) have a long residue period, especially mimesis tobacco herbicides, with a residue period of up to 36 months.

If the soybean stubble uses these two pesticides, or one of them, it will have a certain impact. In addition, there is a kind of pesticide called "Isoweeda pine" (Guang Xuanling) The residual period is also very long, if the amount of pesticide application is too large, it will cause leaf whitening and other pesticide damage of corn, wheat and other grasses.

Others, such as butyl ester, acetochlor, amithane, bendasone, etc., have no effect on the subsequent crop corn.

After I sprayed the soybean sealant and it rained, can I be harmed by the drug.

Due to the lack of professional weeding techniques, some growers use herbicides indiscriminately, causing serious damage or even preventing harvesting. Once bitten by a snake, he was afraid of the well rope for ten years. The negative effects of the misuse of herbicides in shaft stoves have led many soybean growers to prefer to use manual weeding with hoes rather than labor-saving and time-saving chemical herbicides.

Yu Tuan's chemical weeding technology was later applied to soybean crops through some soybean field trials.

Chemical weeding is better than manual weeding. Generally, growers seal the soil with a soil blocking herbicide before planting soybeans. In case of early weeds and soybean seedlings competing for fertilizer, water, and growth space, hindering soybean production.

Commonly used soybean sprout soil sealing herbicides include 50% insecticide, 80% isopropyl emulsion, pentosan, pentosan and other herbicides. In order to expand the spectrum of weeds and expand the scope of weed control, the production of base or slip book adopts compound preparations or two or three single-dose compound forms. At present, the commonly used compound preparations are pentatalolol and paclitaxel.

In the soybean soil mulch, mix 60 grams with 33% pentylene glycol and 20% thiophene sulfonate compounds with water, and spray evenly to start the mu.

If you want to mulch the cultivation, you should first make a medicine and then mulch, then plant soybeans with holes, and then cover the fine soil. It is safe for soybeans. In this case, the herbicide after rain is also safe for soybeans.

However, if we do not use cover cultivation and use other open-field cultivation methods, rainwater washing weeds below the surface of the soil may cause soybeans to be used as a pesticide at present. The main manifestations are: soybean seedling emergence slows down, leaves become narrower, stalks become thinner, and branches decrease.

After the soybean is unearthed, it grows slowly or stops growing.

The compound leaves of soybeans are curled up like a cup. The leaf epidermis is coarse and prickly, and the plant is dwarf and heavily dead. After the occurrence of pesticide damage, soybean can be combined with amino acid foliar fertilizer, 30 alkanol and brassinolide terpolymer, used 2 3 times in a row, soybean can resume growth.

For serious teratogenicity and lack of monopoly seedlings, they can be sown immediately to ensure the basic seedlings per mu and stable yield.

Dear, I'm glad to have your question The information I found for you is: Can soybean control pills be sprayed after 5 hours of rain and rain? The soybean control medicine has been sprayed for 5 hours, and it rains, and the amount of the medicine is reduced by half, and it is sprayed again.

2 hours of rain after the sedan chair is the need to make up the spray, in the medicine closed rock Shen will be written on the above 4-6 hours after spraying the first spray corn should be made up of jujube spray corn control Wang Note: Pay attention to spray high and not low when applying pesticides, sweep over, and avoid re-spraying. In case of rain within 4 hours after spraying, reduce the dosage by half and spray again.

If it rains within 6 hours of spraying, be sure to cut the dosage in half and spray again. Artificial flourishing control technology In the flowering and podding stage of soybean, leaf thinning and topping can be taken for fields that cannot be effectively controlled by chemical flourishing.
