Wheat due to Miaohua
Q: An reader of Anqing City, Anhui Province, came to the telephone on March 9th: The wheat stems have an average of 2 long stems, which are prosperous and can be used to control lodging. Can be used? Some people say that it is possible to use 20 percent of the 100% mefenacetate powder per acre. It is also said that the methothene will only increase the thickness and hardness of the stalks without affecting the development of the wheat ear. Is it true? Answer: There is currently no single agent registered on wheat, with a combination of methothene and paclobutrazol registered for wheat growth regulation. Sichuan Guoguang Agrochemical Co., Ltd. (telephone) 10% carbazole hydrochloride WP, containing paclobutrazol 2.5%, mepyl chloride 7.5%, registered for wheat growth regulation, recommended application concentration of 200 ~ 300 mg / l, generally 60-80 grams per mu water 30 kg spray. If wheat alone is chemically treated with mepyl chloride, it can be used with 98% of the 100% methothene powder per acre. The use of chemical control agents in barley fields is prolonged to prevent the lodging of wheat in the late stage. The application effect is best about one week before the jointing of wheat, which can control the internode length of wheat and increase the lodging resistance of wheat; the wheat can be at the base of the wheat at the latest. One section before the fixed length application. After the first internode of the wheat base, it is not appropriate to control the use of the mepylene-equilibration control agent. On the one hand, the effect of controlling the fall of the control of Wang decreased, and on the other hand, it may affect the development of wheat ear, which in turn leads to a reduction in yield. The average length of the main wheat stalks in the above-mentioned wheat is 2 long and the first internode of the base has been fixed. Do not use other drugs such as mepoxide. The sheath blight often occurs after jointing of wheat. It is suitable for the control of wheat sheath blight such as tebuconazole and other triazole drugs, has a certain inhibition on the growth of wheat, can shorten the length of the internodes of wheat to a certain extent, enhance the wheat The lodging resistance. The above fields can be combined with the control of wheat sheath blight, the administration of tebuconazole and other drugs, usually also have a good control of Wang control effect. If necessary, the “Jinfeng†of Feilong Company (telephone, 13905238390) of the Huai'an Academy of Agricultural Sciences can be sprayed during the earliest stage of wheat in order to reduce the internode length under the ear of wheat, reduce the plant height, and increase the lodging resistance of wheat.
