Description
技术领域
本发明涉及农药复配技术领域，特别是涉及一种含有氟唑磺隆与丙炔氟草胺的除草组合物。
背景技术
氟唑磺隆是磺酰脲类内吸型高效小麦田除草剂，对野燕麦、雀麦、看麦娘等禾本科杂草和多种双子叶杂草有明显防效。其进口名称为彪虎，是一种全新化合物，其有效成分可被杂草的根和茎叶吸收，通过抑制杂草体内乙酰乳酸合成酶的活性，破坏杂草正常的生理生化代谢而发挥除草活性。彪虎可有效防除小麦田大部分禾本科杂草，同时也可有效控制部分阔叶杂草，在小麦体内可很快代谢，对小麦具有极好的安全性。
丙炔氟草胺是日本住友化学工业株式会社创制并开发的N-苯基邻氨甲酞亚胺类除草剂。经研究发现，丙炔氟草胺可抑制原卟啉原氧化酶，可导致光敏作用和细胞膜脂质的过氧化，对细胞膜共嫩和机构造成不可逆的破坏，大田中，茎叶处理后敏感杂草的茎叶坏死，日光照射后死亡，土壤处理后敏感的杂草芽坏死，在短暂的日光照射后死亡。
合理的化学除草剂复配或混配具有扩大除草谱，提高防治效果、延长施药适期、减少用药量、降低药害、减少残留、延缓抗药性的发生与发展等积极特点，除草剂复配或混配是解决上述问题的最为有效的方法之一。我们在室内筛选和田间试验的基础上，筛选出氟唑磺隆与丙炔氟草胺复配，具有明显的增效作用。且关于氟唑磺隆与丙炔氟草胺复配的除草组合物及应用目前尚无人报道过。

具体实施方式
为使本发明的技术方案，目的以及优点更加清楚明白，本发明用以下具体实施例进行说明，但本发明并非局限于这些例子。本发明的效果实验采用室内生测和田间试验相结合的方式，如无特别说明，以下提及的比例都为质量份数比。
实施例：氟唑磺隆与丙炔氟草胺不同配比联合毒力实验。
1.1供试药剂：
96％的氟唑磺隆原药，96％的丙炔氟草胺原药，上述原药均由海利尔药业股份有限公司研发部提供。
1.2试验靶标：
稗草。
1.3实验步骤：
采用盆栽茎叶处理法(NY/T1155.4-2006):在高6㎝、直径9㎝的塑料钵内装定量土，将供试靶标杂草种子15-20粒播种在塑料钵内,盖0.5-1㎝厚的细土后放在温室内培养，待杂草长至2-4叶期进行茎叶喷雾处理,每钵喷液1mL,每处理重复4次,并设不含药剂的处理为对照。处理后试才置于温室内培养，定期观察靶标杂草的生长情况，15d后目测靶标受害症状及生长抑制情况,并称地上部分鲜重或株鲜重，以报表鲜重抑制率评价药剂对靶标杂草的毒力作用。
1.4调查时间：
试验处理15d后目测靶标受害症状及生长抑制情况，并称地上部分鲜重。
1.5数据统计与分析：
根据调查统计，计算鲜重抑制率(％)。
鲜重抑制率P(％)＝(对照鲜重-处理鲜重)/处理鲜重×100％。
联合作用评价方法：
根据Gowing法评价除草剂联合作用方式(NY/T1155.7-2006)，其公式如下：
E0＝X+Y-XY/100
式中,X为氟唑磺隆以某剂量单用时对靶标杂草的鲜重抑制率；
Y为丙炔氟草胺以某剂量单用时对靶标杂草的鲜重抑制率；
E0为氟唑磺隆与丙炔氟草胺二种药剂混用时对靶标杂草鲜重抑制率的理论值；
E为氟唑磺隆与丙炔氟草胺二种药剂混用时对靶标杂草鲜重抑制率的实测值。
评价标准：当E-E0＞10％时表示为增效作用，当-10％＜E-E0＜10％时表示为相加作用，当E-E0＜-10％时表示为拮抗作用。
2.1氟唑磺隆与丙炔氟草胺二种药剂对稗草的毒力测定结果
表1为氟唑磺隆与丙炔氟草胺二种药剂的混合毒力测定结果
毒力试验例表明，按有效成分氟唑磺隆与丙炔氟草胺比例为1:70～70:1稀释时表现出一定的增效作用，其中氟唑磺隆与丙炔氟草胺为1:20～20:1的增效作用最明显。试验结果表明，在室内条件下氟唑磺隆与丙炔氟草胺复配增效效果佳，建议对适宜配比1:20～20:1左右混配制剂进行进一步的田间药效试验，以评价其田间实际应用效果。
3、田间药效试验
试验在河南省小麦田试验基地，土壤肥力一致肥力中等，试验时湿度适中，试验地主要杂草有猪殃殃，雀麦、稗草等，杂草分布均匀。试验结果如下：
表2氟唑磺隆与丙炔氟草胺复配田间防效试验
大田试验结果表明，氟唑磺隆与丙炔氟草胺以3:1比例复配对小麦田禾本科、阔叶草等杂草的防效均较好，根据田间目测，在试验剂量范围内，作物生长正常，未见植株产生药害及异常现象，说明其对玉米是安全的。
综上毒力和大田试验结果验证，本发明含有氟唑磺隆与丙炔氟草胺的除草组合物，主要用于防除小麦田防除阔叶杂草、禾本科杂草，且对靶标作物安全，与单剂相比，本发明除草组合物具有作用机理独特，有用量少，除草普更加广泛，持效期较长，更加环保等明显优点。所以，本发明的研发及推广有着重大的社会意义及环保意义。
