Quiet reporter Wang Yanan Li Minghui correspondent reported hearing no weeding Jinan, peanut field would cut 10% -30%, in serious cases, more than 50%, can achieve the desired herbicidal effect to blindly increase the amount of herbicide, but also result in peanut growing problem of drug residues in products, resulting in the export of peanut frequently limited. How to use herbicides in the peanut field, how much, the recent Provincial Academy of Agricultural Sciences reporter Wang Yanan Li Minghui correspondent reported quiet Jinan information is not weeding, peanut fields should cut 10% -30%, in serious cases, more than 50%, can achieve the desired herbicidal effect to blindly increase the amount of herbicide, but also causes worsening of drug residues in peanut products, often led to limited export of peanut. How to use herbicides in the peanut field, how much, the recent Provincial Academy of Agricultural Sciences to develop a study three kinds of peanut fields of rational use of herbicides commonly used criteria, will rise as the national standard. Peanut is one of China's major oil crops, are also important agricultural exports. Shandong Peninsula is the main producing areas of peanut exports, the average annual export volume of over 70% of total exports. In recent years, our province peanut acreage and production increased year by year, but lower prices, an important reason why the world's major importing countries have increased peanut peanut Drug Residues in monitoring standards, resulting in exports has been hampered. The study's leader, Provincial Academy of Agricultural Plant Protection Research Associate Li told reporters, weeds that affect peanut yield one of the most important factors, herbicide weed control methods as an important one, mainly to the basis Peanut weed the actual situation, rationally determine the type and dose of application. Each peanut fields were vastly different, but as individual households is difficult to have enough information to judge only according to the note seller herbicide spraying, it is easy to over-application, resulting in crop injury, a serious impact on peanuts and derived products quality and safety. This "community of Shandong Peanut weed distribution and integrated control technology" project recently passed the appraisal, it is the national "Eleventh Five-Year" Technology Support Programme "vicious weed prevention and control technology fields," the sub-topics. Lee said that through research projects, specifically the province, especially peanut field weed communities in a vicious weed distribution and succession status of the province peanut common herbicide acetochlor, a imazapyr, fine differences C alachlor residues in the soil digestion law and peanut residue and residue levels, residual risk assessment carried out to develop these guidelines and the rational use of pesticide residue limits, the level of control since then have peanut Drug Residues basis and methods. Research also for different planting methods, different application time, and the distribution of different weed community to form a scientific and effective peanut weed control technology for comprehensive analysis of environmental conditions on herbicide efficacy, and the impact of herbicide phytotoxicity caused by peanut reasons, the formation of the Shandong provincial standard "comprehensive management of weeds in peanut Technical Specification", an extensive demonstration and popularization in the province. Shandong Peanut field advantage for the weed species, developed eight highly efficient and safe herbicides. It is understood that through the project implementation and promotion, can effectively promote the rational use of herbicides, avoid waste and environmental pollution caused by indiscriminate use, delaying weed resistance to antibiotic and the occurrence of community succession, and extended the herbicide market in Shandong life.
