Abstract
本发明提供一种含有二氯喹啉草酮的除草组合物，有效成分由二氯喹啉草酮、三唑磺草酮和砜嘧磺隆组成，所述二氯喹啉草酮、三唑磺草酮和砜嘧磺隆的重量比例为1‑80:1‑60:1‑20。
Description
技术领域
本发明属于农药领域，具体涉及一种含有二氯喹啉草酮的除草组合物及其用途。
背景技术
二氯喹啉草酮是我国自主研发的新型除草剂，主要通过杂草根、茎、叶吸收用于防除禾本科作物尤其是目前比较难防除的稗草、狗尾草、稗草及多种阔叶杂草，对杂草施药后，由叶片或根部吸收，在植物体中上下移行，迅速传到整个植株，导致杂草出现白化后死亡。
三唑磺草酮是HPPD酶抑制剂类化合物，具有优异的生物活性，可以有效防除水稻田多种恶性杂草。该类化合物的作用机制是通过抑制植物体控制光合作用关键色素酶的活性，使其底物转化为尿黑酸过程受阻，从而导致生育酚及质体醌无法正常合成，影响植物体内光合作用正常进行，最终彻底死亡。
砜嘧磺隆，又称玉嘧磺隆，砜嘧磺隆为乙酰乳酸合成酶(ALS)抑制剂，即通过抑制植物的乙酰乳酸合成酶，阻止支链氨基酸的生物合成，从而抑制细胞分裂。其除草特点是可用于防除玉米田大多数一年生或多年生禾本科杂草和部分阔叶杂草。
合理的化学除草剂混配具有扩大杀草谱，提高防除效果、减少用药量、降低要害、减少残留、延缓抗药性的发生与发展等特点，符合国内农药企业的现状，并且不同农药之间的交互使用能够延缓作用物抗药性的产生，具有较为理想的使用效果，目前，关于二氯喹啉草酮、三唑磺草酮和砜嘧磺隆的复配组合物及应用尚无人报道。
