Most gramineous plants are relatively drug-resistant, and most dicotyledonous crops, weeds, and shrubs except cruciferous are sensitive to this drug, and can control most dicotyledonous weeds, shrubs, and the effect on cruciferous weeds Difference
However, its residual period is long, and it is not safe for sensitive crops after a single effective dosage is large, and its use on rapeseed is extremely limited

Abstract
A synergistic herbicidal pesticide composite consists active ingredients and auxiliary ingredients acceptable in pesticide, wherein the active ingredients are flufenacet and picloram of which weight ratio is (160-2):1. The combination of the two active ingredients in the composite generates synergy; and the composite is especially suitable for the weeding of the rape field, the wheat field and the corn field, and can prevent and control various latifoliate weeds; the herbicidal spectrum is expended, the herbicidal effect is improved effectively, the cost is reduced and the safety to crops is improved.
Description
technical field [0001] The invention relates to a herbicide pesticide composition, which is especially suitable for weeding in rape fields, wheat fields and corn fields. Background technique [0002] Flufenacet is an aryloxyamide herbicide with a chemical structure as shown in formula (I), and was developed by Bayer in 1988. Its mechanism of action is mainly to inhibit cell division and growth. A large number of field experiments have been done in the United States, Europe, South Africa, Asia, South America and other regions. some broadleaf weeds. It is used for weeding in corn and soybean fields before planting or pre-emergence, weeding before planting or pre-emergence of potatoes and sunflowers, and post-emergence weeding of wheat, barley, rice, corn, etc. However, when flufenacet is used alone, the stem and leaf treatment activity is relatively low, and the herbicidal spectrum is narrow, and the use cost per mu is relatively high. [0003] Picloram is a pyridine carbo...
