Description

含甲基立枯磷的棉苗病害防治的药肥复合型粉状种衣剂 Fertilizer containing composite powder Cotton Seed disease control of tolclofos

技术领域 FIELD

[0001] 本发明涉及农药加工技术领域,尤其涉及一种具有棉苗病害防治和壮苗效果的种衣剂,特别涉及一种含甲基立枯磷的棉苗病害防治的药肥复合型粉状种衣剂。 [0001] The present invention relates to the technical field of pesticide processing, and more particularly having Cotton Seed and seedling disease control effect, particularly to a disease control Cotton tolclofos-containing composite powder Fertilizer like seed coating.

背景技术 Background technique

[0002]甲基立枯磷是一种广谱内吸性杀菌剂。 [0002] tolclofos-methyl, within a broad spectrum fungicide. 其吸附作用强,不易流失,持效期较长。 Its strong adsorption, easy loss, long persistence. 被广泛用于防治土传病害,对立枯病、枯萎病、菌核病、根腐病、十字花科黑根病和褐腐病均有显著的防治效果。 Is widely used to control soil-borne diseases, for blight, Fusarium, Sclerotinia, root rot, black root rot and cruciferous brown rot showed a significant control effect. 当前,甲基立枯磷用于棉花苗期病害防治上主要与福美双、多菌灵等复配制成悬浮种衣剂。 Currently, tolclofos-methyl for the control of cotton seedling diseases mainly thiram, carbendazim and other complex formulated as flowable concentrate. 但这一制剂主要有以下四方面的缺点: But the main drawback of preparations the following four areas:

一、贮存稳定性差。 A, poor storage stability. 悬浮剂作为一种将固体成分以4微米以下的微粒均匀分散于水中的固液混合物,由于配方、加工技术、保存条件等原因,其在贮存过程中容易出现析水等固液分层现象,导致固体沉淀,严重时因沉淀结块而无法摇匀倒出。 A suspending agent as a solid content to 4 m or less fine particles are uniformly dispersed in the solid-liquid mixture of water, due to the formulation, processing techniques, storage conditions, etc., which is prone to syneresis solid-liquid stratification in storage, resulting in solid precipitation, severe caking due to precipitation and can not shake poured. 析水分层造成产品在使用中施药不均匀,使用困难等。 Analysis of the product caused by moisture stratification in use administration unevenness, difficult to use and the like.

[0003] 二、产品不耐低温。 [0003] Second, the product cold intolerance. 作为以水为载体的悬浮剂,在低温地区容易结冰而破坏产品的理化性状。 As the water as a carrier of the suspension, easy to freeze and destroy the physical and chemical properties of the product in the low-temperature region. 然而我国种衣剂的使用范围又是以西北及东北等冬季严寒地区为主,这些地区在冬天如何贮藏悬浮种衣剂一直是困扰生产企业和客户的一个难题。 However, the use of a range of seed coating and is mainly northwest and northeast winter cold areas, where in the winter how to store suspension Seed has been a problem plagued manufacturers and customers. 为了解决这个难题,技术上是降低产品的冰点,如加入丙三醇等防冻剂,但这只能使冰点降到零下4°C左右,如要使冰点达到零下10°C以下,则防冻剂的成本会大大的提高,而且防冻剂对种子芽率及安全性的影响还有待长期验证;贮存上则是通过供暖以提高仓库的温度,但这大大提高了企业的贮存成本。 To solve this problem, technology to reduce the freezing point of the product, such as glycerin antifreeze added, but only down to about the freezing point so that minus 4 ° C, such as to make the freezing point below 10 ° C below zero, the antifreeze the cost will be greatly improved, and the influence of antifreeze on seed germination rate and the long-term safety has yet to be verified; the store is to raise the temperature by heating the warehouse, but it greatly increases the storage costs.

[0004] 三、壮苗效果差。 [0004] Third, the seedling poor. 目前含甲基立枯磷的种衣剂都只有防治苗期病害的保苗功能,而没有壮苗功能。 Currently seed coating containing tolclofos have only the function control seedling diseases seedling without functional seedlings. 为了使产品同时具有保苗和壮苗功能,则必须加入磷钾等作物生长所需营养成分。 In order to make products having both functions seedling and seedlings, phosphorus and potassium and the like must be added nutrients required for the growth of crops. 但是加入磷钾等肥料,这些强离子盐化合物则严重破坏悬浮体系的离子平衡,剧烈地降低悬浮剂的稳定性。 However, addition of phosphorus and potassium fertilizers and the like, which is strong ionic salt compounds severely disrupt the ionic balance of the suspension system, dramatically reducing the stability of the suspension.

[0005] 四、含量低。 [0005] Fourth, the low levels. 作为以水为载体的悬浮剂,为了确保良好的稳定性能,配方中需加入大量的分散润湿等助剂及载体水,这导致产品配方中有效成分的含量无法提高,从而降低产品的包衣比例。 As suspending agent to water as the carrier in order to ensure good stability, the formulation must be added a large amount of a wetting dispersing water and other additives and the carrier, which leads to an active ingredient content of the product formulation can not be increased, thereby reducing the coated product proportion. 当前含甲基立枯磷悬浮种衣剂的包衣比例只达到1:30〜60,使单位重量种子包衣所需种衣剂量很高,严重增加了种衣剂运输成本。 The current ratio of coating suspension containing tolclofos Seed only reaches 1: 30~60, seed coating so that the coating amount of the desired very high, serious seed coating increases the transportation cost per unit seed weight.
