Description

一种杀线虫组合物及其用途
技术领域
本发明涉及农药技术领域，具体说是一种杀线虫组合物及其用途。
背景技术
线虫大多生活在土壤中，有的寄生在植物体内，通过土壤或种子传播，能破坏植物的根系，或侵入地上部分的器官，影响农作物的生长发育，并且间接传播其他微生物引起的病害，造成农业上很大的经济损失。线虫由于寄生部位隐蔽，很难被清除干净，并且现有的杀线虫剂容易产生药物抗性，更是加剧了线虫防治的困难。
目前效果比较好的杀线虫剂很少，仅有十余种，并且由于现有的效果较好的杀线虫剂对人畜的毒性较高，有些品种对作物有药害，影响其使用，所以新型、高效、对环境友好的杀线虫剂亟待开发。
发明内容
为解决上述问题，本发明的目的是提供一种杀线虫组合物及其用途。
本发明为实现上述目的，通过以下技术方案实现：
一种杀线虫组合物，组合物中含有有效成分A和B，A和B的质量比为20：1~1：20；所述A为噻唑膦、阿维菌素、糠醛、棉隆、氟吡菌酰胺、丁硫克百威、威百亩、厚孢轮枝菌、甲氨基阿维菌素、淡紫拟青霉或氟噻虫砜中的任一种；所述B的结构式为式Ⅰ或式Ⅱ，如下所示，式Ⅰ为
；
式Ⅱ为
。
优选的，A和B的质量比为10：1~1：10。
进一步优选的，A和B的质量比为5：1~1：5。
优选的，化合物B的结构式I为
。
优选的，杀线虫组合物可加工成能够进行滴灌、冲施的液体剂型和撒施的固体剂型，可溶液剂、水乳剂、乳油、水剂、颗粒剂等。
优选的，杀线虫组合物为以下成分组成的可溶液剂：化合物B为式I 10份，糠醛10份，仲醇聚氧乙烯醚8份，聚氧乙烯烷基胺1份，丙二醇20份和N-甲基吡咯烷酮51份。
优选的，该杀线虫组合物为以下成分组成的可溶液剂：化合物B为式I 15份，棉隆18份，羟乙基醋酸酯8份，聚氧乙烯醚硫酸酯盐3份，松脂油2份，辛葵酸甲酯3份，N-甲基吡咯烷酮51份。
优选的，该杀线虫组合物为以下成分组成的颗粒剂：化合物B为式Ⅱ 3份，噻唑膦18份，木质素磺酸盐1份，烷基萘磺酸盐甲醛缩合物5份，白炭黑5份，尿素5份，硫酸铵10份，凹凸棒土54份。
本发明还包括杀线虫组合物的用途，用于杀灭植物寄生性线虫，包括根结线虫、茎线虫、包囊线虫、根腐线虫和松木线虫。
本发明相比现有技术具有以下优点：
本发明的杀线虫组合物由新型的含内酯环的杀线虫剂和现有的杀虫剂、杀菌剂组成，具有良好的杀线虫活性，对人畜的毒性小。本发明的杀线虫组合物对根结线虫的卵与二龄幼虫有很好的防治效果，尤其能很好地抑制黄瓜、番茄、烟草、大豆等根结线虫卵的孵化；毒性较低，在农作物中的残留少，对人、畜的危害性小，很好解决了现有的杀线虫剂毒性较大，在作物中的残留较多的问题，提高了农业生产的安全性；在较长时间内使用害虫不会对本发明的杀线虫剂产生抗体，具有很好的杀虫效果；可用于作物的各个生长时期，可在植物幼苗期或幼苗移栽前进行土壤处理，顺水冲施、滴灌和撒施；本发明的杀线虫组合物，能够进一步改良现在农业生产中常用杀线剂的活性，减少组合物中两个有效成分的用药量，减轻环境压力，延长化合物的使用寿命。本发明的杀线虫组合物的共毒系数最高可达到379，具有较好的协同增效作用。
