Recently, during the weeding period of rice, there are alfalfa and Qianjin in the direct seeding field of rice. However, some farmers have found that there are also borer pests when weeding. We know that herbicides are not the same as insecticides, so if we want to weed and remove insects, Can these two agents be mixed? Let's take a look at the following. 1. Can herbicides and pesticides be mixed? Herbicides can be mixed with pesticides, but they should be scientific and principled. However, it is not recommended to add insecticides and fungicides, especially organophosphorus pesticides, when herbicides are used. It is forbidden to be mixed with herbicides. Second, the correct practice of adding pesticides to herbicides Herbicides add pesticides, follow the principle of pesticide mixing, organic phosphorus and propanol and carbamate insecticides must not be mixed to avoid phytotoxicity. At the same time, in the case that safety cannot be ensured, a small-scale test is first carried out. First, whether the mixed dilution of the two is reactive (precipitation, stratification), whether it is stable, and whether the application of the drug is toxic. 3. Which herbicides can be mixed with pesticides? 1. Herbicides, insecticides and fungicides contain these components and can be mixed: herbicides such as pyridinium, quinclorac, bis-chlorinated, cyhalofop, and penoxsulam, imidacloprid, Insecticides such as pymetrozine and avermectin, and fungicides such as tricyclazole, difenoconazole, hexaconazole, and prochloraz can be compounded. Therefore, cyhalofoprin can be mixed with herbicides and has little effect on the efficacy. 2, do not recommend herbicides and fungicides mixed with herbicides: phoxim, triazophos, malathion, etc. in organic phosphorus, zhongdingwei, butyl thiocarbamate in carbamate Etc., especially the enemy, in recent years, due to the increased resistance of valerian, it is particularly difficult to prevent. The application of pesticide-containing pesticide products in rice is gradually increasing. This drug can not only be mixed, and it can not be used in two weeks after use. , carbamate pesticides. Fourth, rice irrational mixed use of phytotoxicity solutions 1. Determine whether the drug is harmful. The abnormal symptoms of rice appear in the late stage of application, and the abnormal symptom sites and field distribution are observed. If the disease occurs, the leaves are yellow, the heart leaves are severely deformed, the distortion, the growth stagnation or even death, and the causes of the phytotoxicity are analyzed. 2. Lightly affected fields, strengthen water and fertilizer management, and appropriate application of nitrogen fertilizer; for fields with heavier phytotoxicity, spray Bibi, Chi B, B, and other drugs to alleviate phytotoxicity, and appropriately add potassium dihydrogen phosphate. , high quality foliar fertilizer containing amino acids. 3. If the phytotoxicity caused by misuse or excessive use of organophosphorus or carbamate pesticides, spray 0.5%-0.1% of lime water, soapy water and other alkaline substances for detoxification, preferably spraying ammonium bicarbonate Alkaline fertilizers and pesticides not only detoxify, but also promote rice growth. The above is about the mixed application of herbicides and weeds in rice. For rice growers, weeds and pests have serious harm to rice yield. Therefore, the use of herbicides and pesticides is essential, and the mixture of the two can save time. Labor-saving, but pay attention to the pesticide mixture must be scientifically carried out, can not be arbitrarily matched, so as to avoid phytotoxicity.
