Abstract
The invention discloses a wheat seed treating agent composition containing silthiopham, which solves the technical problems that a bactericidal spectrum is narrow, the usage amount per mu is high and the cost is high when silthiopham and fludioxonil are respectively used for preventing and treating wheat diseases. According to the technical scheme, the composition comprises the following components by weight percent: 10-80% of effective components, 5-15% of an auxiliary and 5-80% of fillers, wherein the effective components include silthiopham and fludioxonil by a weight ratio of (1:20)-(20:1). The wheat seed treating agent composition has the technical effects of being good in environment compatibility, low in toxicity and safe to humans and livestock; the composition is capable of preventing and treating the wheat diseases such as stinking smut, winter scald, snow mold, rhizoctonia solani kuhn, fusarium solani, septoria nodorum and flag smut which can be respectively prevented and treated by the silthiopham and the fludioxonil when the silthiopham and the fludioxonil are used respectively; besides, the composition has a remarkable synergism effect on gaeummanomyces; the usage amount per mu is lower than that when the silthiopham and the fludioxonil are used respectively, so that the usage amount is lowered and the cost is saved.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of composition, particularly a kind of wheat seed agent composition that contains Silthiopham.
Background technology
But Silthiopham is used for the generation of wheat seed dressing strong inhibition take-all, but not good enough to the control efficiency of other diseases of wheat.Fludioxonil is a kind of seed treatment commonly used; by suppressing the relevant transfer of glucose phosphorylated; and the mycelial growth of Antifungi; finally cause germ dead; be used for wheat seed dressing and can effectively prevent and treat the diseases such as the bunt of wheat, snow mold, snow mold, banded sclerotial blight, root rot, full rot, glume blight, stem smut, wherein will differ from than Silthiopham the preventive effect of full rot.Not only fungicidal spectrum was narrow when control wheat diseases Silthiopham and fludioxonil used respectively, and every mu used dose is large, cost is higher, therefore, the seed treatment composition of seeking a kind of more economical and efficient is the study hotspot of pesticide field.
Summary of the invention
The objective of the invention is in order to solve Silthiopham and fludioxonil and to use respectively that not only fungicidal spectrum is narrow, and every mu of used dose is larger, the technical problem that cost is higher, in order to address this problem, we have designed a kind of wheat seed agent composition that contains Silthiopham, not only can prevent and treat the disease that to prevent and treat separately when Silthiopham and fludioxonil use respectively, such as the bunt of wheat, snow mold, snow mold, banded sclerotial blight, root rot, glume blight, the diseases such as stem smut, and obvious to full rot synergy, and every mu of used dose when using respectively than Silthiopham and fludioxonil used dose all lack, saved cost.
The present invention for realizing the concrete technical scheme that goal of the invention adopts is: a kind of wheat seed agent composition that contains Silthiopham, key is: each composition comprises by weight percentage in the described composition: active ingredient 10～80%, auxiliary agent 5～15%, filler 5～80%, wherein active ingredient comprises Silthiopham and fludioxonil, and the weight ratio of Silthiopham and fludioxonil is (1: 20)～(20: 1).
The invention has the beneficial effects as follows: Silthiopham and fludioxonil compatibility are done the wheat seed agent composition; both are mutually collaborative; can be simultaneously from two different target point effects; for seed provides omnibearing protection; its Environmental compatibility is good; toxicity is low, to the person poultry safety, belongs to the wheat seed agent composition of broad-spectrum high efficacy.Not only can prevent and treat the disease that to prevent and treat separately when Silthiopham and fludioxonil use respectively, such as diseases such as the bunt of wheat, snow mold, snow mold, banded sclerotial blight, root rot, glume blight, stem smut, and used dose all lacked when obvious and every mu of used dose used respectively than Silthiopham and fludioxonil to full rot synergy, reduce dosage, saved cost.
