Abstract

The invention provides a herbicide combination, containing the effective constituents of picloram or picloram ester, clopyralid or clopyralid ester and as well as one or more varieties of triketone; the weight ratio of the three constituents is 0.1:1:20-20:1:0.1. The combination contains at least one surfactant. The combination can be used to prepare emulsifiable solution, liquor, thick emulsion, microemulsion, wettable powder, water suspending agent, oil suspending agent, water-dispersible granules, soluble powder or granules, and is used to prevent and control Gramineae and broad-leaved weeds which have grown for one year or more than one year in the corn field.

Description

Technical field [0001] The present invention belongs to the field of agricultural herbicides, and more specifically, relates to a herbicide composition containing atratridine or its salt or its ester, clopyralid or its salt or its ester and triketones and its application. Background technique [0002] Pilotrafen was developed by Dow Company of the United States and is mainly used to control broadleaf weeds and shrubs in young coniferous woodlands. It is a systemic herbicide that is rapidly absorbed by leaves and roots and is conducted within the plant. It acts on nucleic acid metabolism, causing plants to produce excess nucleic acids, causing some tissues to transform into meristems, causing deformed growth of leaves, stems and roots, exhaustion of stored substances, embolization or rupture of vascular tissue, and gradual death of plants. [0003] Clopyralid is a systemic post-emergent herbicide that effectively controls Asteraceae, Leguminosae, Solanaceae and Apiaceae weed...
