Wheat field herbicide remedy

Before the winter wheat field was removed, it was particularly important to avoid the risk of phytotoxicity.
1 Acetochlor. After germination, acetochlor or its compound preparation (such as thiabendazim) can be used in 3-4 days after the drug, and it is easy to appear incomplete or no seedlings. .

2 isoproturon. The application period is wide, and it can be applied from pre-emergence to pre-union of wheat, but the herbicidal effect is the best before weed emergence to the third leaf stage. Severe frosty weather within half a month after the application of isoproturon may cause heavier phytotoxicity to wheat that has not been subjected to low temperature training, and wheat seedlings may have leaf chlorosis and growth inhibition. Severe frost appears in a short time after application, and wheat is more seriously damaged, and even dead. The application of isoproturon and its compound preparation in the wheat field generally requires no daily minimum temperature of less than 0 °C within 1 week after application.

3 methyl disulfuron. Some wheat varieties may have temporary yellowing or dwarfing in the early stage of growth. Generally, the yellowing phenomenon will naturally disappear after the rejuvenation, and the dosage will exceed the standard. Improper application may cause serious phytotoxicity. The damaged wheat seedlings will yellow and grow. Suppressed, severe dry dead seedlings. After over-application in spring, the wheat seedlings can not resume growth for a long time, which will seriously affect the differentiation of wheat ears and timely heading. Therefore, the application in spring should be more cautious.

4 acetylene ester. When the dosage of the active ingredient per acre reaches 135 grams, it will obviously inhibit the growth of wheat seedlings, but the wheat seedlings can recover quickly. If the temperature is low after application, especially in the case of continuous cold weather and large temperature changes, the phytotoxicity is more likely to occur. The growth of wheat seedlings was inhibited. Even after the application of clodinafop in winter and spring in some years, the yellowing of wheat leaves after application resulted in a large number of dead seedlings.

5 fluoxetine. A safer broadleaf weed herbicide, in a drug-resistant plant such as wheat, the drug can bind to the conjugate to lose toxicity and thus be selective. However, if the dose is blindly increased, it is prone to phytotoxicity. Generally, symptoms will appear 2 to 3 days after application. The main manifestations of wheat are yellowing, plant deformity, and distortion. For example, 450 g/L of flupiroxyacetic acid emulsifiable concentrate per acre may cause serious phytotoxicity to wheat. There are even dead seedlings. Therefore, the general safe use dose is 50 ml to 70 ml.

6 2 A 4 chlorine. Before the 4 leaf stage of wheat, 2 to 4 chlorine was used, which was prone to phytotoxicity and formed onion tube leaves. After the jointing of wheat, it is easy to cause the onion tubular curl and the ear deformity.
