Abstract
本发明涉及一种控制复合病害的组合物,其含有式(I)化合物和选自咯菌腈、噁霉灵、硫酸铜钙中的至少一种杀菌剂作为有效成分。所述组合物可同时防除线虫类、刺足根螨等生活在土壤和/或种子中的害虫以及土壤和/或种子传染性病害。
Description
技术领域
本发明涉及一种控制复合病害的组合物,其可同时防除线虫类、刺足根螨等生活在土壤和/或种子中的害虫以及土壤和/或种子传染性病害。
背景技术
线虫通过直接摄食损害、传染病毒和促进细菌和真菌污染而破坏作物。线虫引起的根损害可引起作物产量和质量的显著降低,并且从而导致消费者的成本增加。
人们希望得到一种组合物,其可同时防除线虫类、刺足根螨等生活在土壤和/或种子中的害虫以及土壤和/或种子传染性病害,而且与单独施用一种活性成分相比,组合物具有强化的增效防除效果。
式(I)化合物由WO2013/143811已知。其中记载了其用于防治动物害虫的用途。特别是其对线虫的控制显示良好的活性。
但是,尚不知道将式(I)化合物与特定的杀菌剂组合时,对于同时防除生活在土壤和/或种子中的害虫以及土壤和/或种子传染性植物病害是否都可发挥协同增效的效果。
发明内容
本发明目的是提供一种控制复合病害的组合物,其可同时防除线虫类、刺足根螨等生活在土壤和/或种子中的害虫以及土壤和/或种子传染性病害。
本发明人在为解决这一课题而反复研究。发现将式(I)化合物与咯菌腈、噁霉灵、硫酸铜钙组合,可以取得以上预期的效果,从而完成了本发明。
本发明一种控制复合病害的组合物是采取以下技术方案实现:
本发明提供一种控制复合病害的组合物,其含有式(I)化合物和选自咯菌腈、噁霉灵、硫酸铜钙中的至少一种杀菌剂作为有效成分。
特别强调包含式(I)化合物和咯菌腈的组合物,且所述式(I)化合物和咯菌腈的重量配比为:10:1-1:200,更优选5:1-1:100,更优选1:1-1:50。
特别强调包含式(I)化合物和噁霉灵的组合物,且所述式(I)化合物和噁霉灵的重量配比为:50:1-1:1000,优选10:1-1:500,更优选1:1-1:250。
特别强调包含式(I)化合物和硫酸铜钙的组合物,且所述式(I)化合物和硫酸铜钙的重量配比为:1:1-5000,更优选1:10-1:2500,更优选1:50-1:2000,更优选1:50-1:1000。
术语“组合物”代表式(I)的化合物和咯菌腈、噁霉灵、硫酸铜钙的各种组合,例如以单一预混物(ready-mix)的形式、以由各个活性成分的单独制剂组成的结合喷雾混合物(例如桶混物(tank-mix))的形式,以及在适当短的时间段,例如几小时或几天内相继地施用。
本发明的组合物对于防除生活在土壤和/或种子中的害虫的效果和防除土壤和/或种子传染性病害具有增效的作用。该作用具有从各单独活性成分具有的各种病虫害防除特性中无法预测到的效果。与单独使用各活性成分相比,本发明的有用性,在明显增强病虫害的防除效果、特别是土壤中的病虫害防除效力的同时,还具有速效性效果的特点。
本发明的组合物对防除生活在土壤和/或种子中的植物寄生性线虫类有特别优异的防效。
因此,本发明还涉及一种将本发明的组合物用于防除生活在土壤和/或种子中的害虫的用途,尤其是防除以下植物寄生线虫的用途。例如:
根结线虫属种类(Meloidogyne species),如根结线虫(root knotnematodes)、北方根结线虫(Meloidogynehapla)、南方根结线虫(Meloidogyneincognita)、爪哇根结线虫(Meloidogynejavanica)、花生根结线虫(Meloidogynearenaria);
球孢囊线虫属种类(Globodera species),如马铃薯金线虫(Globoderarostochiensis);
异皮线虫属种类(Heterodera species),如禾谷孢囊线虫(Heteroderaavenae)、大豆胞囊线虫(Heteroderaglycines)、甜菜胞囊线虫(Heteroderaschachtii)、红三叶异皮线虫(Heteroderatrifolii);
刺线虫属种类(Belonolaimus species),如刺毛线虫(Stingnematodes)、长尾刺线虫(Eelonolaimuslongicaudatus);
伞滑刃属种类(Bursaphelenchus species),如松树线虫(Pine nematodes)、松材线虫(Bursaphelenchusxylophilus);
茎线虫属种类(Ditylenchus species),如茎及鳞球茎线虫(Stem and bulbnematodes)、腐烂茎线虫(Ditylenchus destructor)、鳞球茎茎线虫(Ditylenchusdipsaci);
长针线虫属种类(Longidorus species),例如针状线虫(Needle nematodes)、横带长针线虫(Longidoruselongatus);
短体线虫属种类(Pratylenchus species),例如腐线虫(Lesion nematodes)、花斑短体线虫(Pratylenchusneglectus)、穿刺短体线虫(Pratylenchuspenetrans)、弯曲短体线虫(Pratylenchuscurvitatus)、古氏短体线虫(Pratylenchusgoodeyi)。
特别地,本发明的组合物对防除根结线虫属、异皮线虫属以及短体线虫属线虫及其幼虫和卵显示令人惊喜的“增效”作用。
更加特别地,本发明的组合物对防除南方根结线虫(Meloidogyneincognita)、花生根结线虫(Meloidogynearenaria)、马铃薯金线虫(Globoderarostochiensis)、禾谷孢囊线虫(Heteroderaavenae)、大豆胞囊线虫(Heteroderaglycines)、甜菜胞囊线虫(Heteroderaschachtii)、松材线虫(Bursaphelenchusxylophilus)、腐线虫(Lesionnematodes)及其幼虫和卵显示令人惊喜的“增效”作用。
