The present invention relates, inter alia, to a method of improving the tolerance of a plant, which has been genetically engineered to over express a p-hydroxyphenylpyruvate dioxygenase (HPPD), to a HPPD inhibiting herbicide, said method comprising applying to said plant a water-soluble iron-containing compound. The present invention further relates to a method of selectively controlling weeds at a locus, the locus comprising weeds and crop plants, the crop plants having been genetically engineered to overexpress a HPPD which confers tolerance to a HPPD-inhibiting herbicide, the method comprising application to the locus of (i) a weed controlling amount of a HPPD-inhibiting herbicide and (ii) a water-soluble iron-containing compound. The present invention further relates to herbicidal compositions comprising a HPPD-inhibiting herbicide and a water-soluble iron-containing compound.
本发明尤其涉及一种提高植物对抑制 HPPD 除草剂的耐受性的方法,该植物已被基因工程改造为过度表达对羟苯基丙酮酸二氧 化酶(HPPD),所述方法包括向所述植物施用含铁的水溶性化合物。本发明还涉及一种在基因座上选择性控制杂草的方法,所述基因座包括杂草和作物植物,所述作物植物经基因工程改造以过度表达一种HPPD,该HPPD可赋予对HPPD抑制性除草剂的耐受性,所述方法包括向所述基因座施用(i)杂草控制量的HPPD抑制性除草剂和(ii)水溶性含铁化合物。本发明还涉及除草组合物,该组合物包含 HPPD 抑制除草剂和水溶性含铁化合物。
