Description
Technical Field
The invention belongs to the technical field of pesticide herbicides, and particularly relates to a herbicide composition containing cyhalofop-butyl and sulfentrazone.
Background
The rice is the first large grain crop in China, the annual planting area is about 4.5 hundred million acres, and the rice is the most main consumer variety in grain. According to the characteristics change of the consumption of the grain and the quantity of safe cultivated land of Chinese residents, the rice consumption of the Chinese residents is 68.2 kg in 2011 and accounts for 54.7 percent of the total consumption of the grain. The main weeds in the paddy field are cockspur grass, moleplant seed, cudweed herb, piemarker, large crabgrass, black nightshade, purslane, chenopodium album, paspalum distichum, leersia hexandra and the like; and the like. The grass damage seriously threatens the normal growth of the rice and is an important obstacle for restricting the high, stable and high yield of the rice. Weeds compete with rice for water, nutrients, illumination and space, so that the growth environment of the rice is deteriorated, and the normal growth of the rice in the seedling stage is influenced. In general years, the yield of the rice can be reduced by 1-2 due to the harm of weeds, and the yield can be reduced by 3-5 in severe cases. The weed control in paddy fields is an important link in the production of paddy rice.
The herbicide is a common measure for preventing and controlling weeds in the paddy field at present, and has important effects on promoting the increase of the yield of paddy rice and saving the planting cost. However, the herbicide is popularized and applied in a large area for a long time, so that the problems of weed resistance, population succession and phytotoxicity existing in the chemical prevention and control of farmland weeds are gradually serious, and the high yield and harvest of rice and the safety of afterreap crops are seriously influenced. The long-term use of a single herbicide for preventing and killing can cause the number of sensitive weeds to be reduced, the number of insensitive or malignant weeds to be increased, the weed community is changed, and the harvest of the rice crop yield is seriously influenced.
Sulfentrazone, the English name Sulfentrazone, the alias N- (2, 4-dichoro-5- (4- (difluoromethyl) -4, 5-dihydo-3-methyl-5-oxo-1H-1, 2,4-triazol-1-yl) phenyl) methanesulfonamide, the product name N- (2,4-Dichloro-5- (4-difluoromethyl-4, 5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl) phenyl) methanesulfonamide, the molecular formula C11H10Cl2F2N4O3S, molecular weight 387.19, CAS registry No. 122836-35-5. Belongs to a low-toxicity weed removing agent. Raw medicine rat acute oral LD50>2855 mg/kg, and LC504.14 mg/l by acute inhalation, the medicine has slight irritation to rabbit skin, irritation to rabbit eye, and low toxicity to fish. Belongs to protoporphyrinogen oxidase inhibitors. By inhibiting protoporphyrinogen oxidase, excessive protoporphyrin IX, which is a photosensitizer and causes active oxygen to be generated in the plant cell, finally causes the cell membrane, the tonoplast membrane and the like to be broken, the intracellular solute to be exuded and dried up and dead. The half-life period of the soil is 110 + 280 days, and the stem and leaf treatment and the soil treatment can be performed. Is suitable for waterThe herbicide is used for preventing and treating 1-year-old broadleaf weeds, gramineous weeds, nutgrass flatsedge and the like in fields such as rice, sorghum, soybeans, peanuts and the like, such as morning glories, amaranthus retroflexus, quinoa, stramonium, crab grass, green bristlegrass, goosegrass herb, cyperus rotundus and the like.
Cyhalofop-butyl (cyhalofop-butyl), chemical name: (R) -2- [4 (4-cyano-2-fluorophenoxy) phenoxy ] -propionic acid butyl ester, molecular formula C20H20FNO 4; molecular weight 357.4; CASNO 122008-85-9. Cyhalofop-butyl is the only variety with high safety to rice in aryloxy-phenoxy-propionic acid herbicides, and is a systemic conductive herbicide. Absorbed by leaves and leaf sheaths of plants, phloem conducts, accumulates in meristematic regions of plants, resists acetyl coenzyme a carboxylase (ACCase), stops fatty acid synthesis, prevents cell growth and division, destroys lipid-containing structures such as membrane systems, and finally causes plant death. The weed dies slowly from the absorption of cyhalofop-butyl, which generally takes 1-3 weeks. Cyhalofop-butyl has excellent selectivity to rice, the selectivity is based on different metabolic rates, and cyhalofop-butyl can be rapidly degraded into a diacid state without activity to acetyl coenzyme A carboxylase in a rice body, so that the cyhalofop-butyl has high safety to rice. Because it degrades rapidly in soil and in typical paddy field water, it is safe for succeeding crops. Cyhalofop-butyl is mainly used for preventing and removing important gramineae weeds, has high efficiency on moleplant seeds, has certain control effect on low-age barnyard grass, and can also prevent and remove crabgrass, paspalum distichum, green bristlegrass, eleusine indica, alopecurus aequalis and the like. Is not effective on Cyperaceae weeds and broadleaf weeds.
The development of new herbicides is expensive and has long period, and compared with the development and research of efficient, low-toxicity and low-residue compounding and mixing, the method has the advantages of low investment and short development period. The reasonable compounding or mixing of the chemical herbicide has the advantages of expanding a weed control spectrum, improving the control effect, prolonging the pesticide application period, reducing the dosage, reducing the risk of phytotoxicity, reducing residues, delaying the occurrence and development of drug resistance and drug resistance of weeds and the like, so that the selection of the proper compounding or mixing of the herbicide is one of the most effective and economical methods for solving the problems; however, because the action mechanism between pesticide blending is complex, whether the synergy is influenced by various factors after combination is verified only by depending on experimental results, and the expectation cannot be carried out.
