我国种衣剂的研究进展 总被引:1,自引:0,他引:1
阐述我国种衣剂的农药原药、肥料、生长调节剂、成膜剂及配套助剂等方面的研究进展。分析得出我国种衣剂研究存在着:①种衣剂中农药原药对于环境及人类的毒害作用较高;②研究多注重产量问题,而对于机理研究较少;③对于低毒低残留的种衣剂产品无统一标准。未来种衣剂将向着低毒低残留、有效成分含量高方向发展,且生物防治剂的大量引入亦将是未来种衣剂的发展趋势。 相似文献

目前我国使用的农药品种主要为有机磷、氨基甲酸酯和菊酯等。其中有机磷农药已成为我国农药残留急性污染事件的元凶。虽然大多数氨基甲酸酯类农药属中、低毒性,但其中的呋喃丹、涕灭威等却属高毒农药。长期以来农药的大面积使用和滥用,使得农药残留严重威胁到人类食品的安全性。中国科学院大连化学物理研究所开发的便携式荧光探针农药残留检测仪,可满足我国基层部门对农药残留现场检测和农药残留检测室筛选分析的迫切需要。 相似文献

目前,中国对于蔬菜中农药残留的测定技术己获得巨大的进展,但对于复杂实验中的多种类农药残留成分的精确的分析还有待提高。本研究从实际问题出发,以气相色谱仪器为工具,建立蔬菜中农药残余的定性定量分析方法,测定日常食用黄瓜中农药残留含量。 相似文献

In the laboratory three types of pheromone traps for the Mediterranean Flour Moth,Ephestia kühniella were tested. The trap of the Albany International Corp. was compared with the Detia Mottenindikator and a trap of the Institute for Pesticide Research in Wageningen. In separated series of trials with paired traps, all six possible combinations between traps and lures were tested. The direct comparison between Detia Mottenindikator and the Albany trap revealed no significant difference in moth catch. But the shape of the Detia trap is better than the Albany one, whereas for the lures the reverse holds true. The best combination is therefore Detia trap/Albany lure. Significant fewer moths were caught with the trap of the Institute for Pesticide Research than with the Albany trap. 相似文献

Pesticide and nutrient runoff from agricultural fields is a socio-environmental problem in the Midwestern United States. Riparian
forest buffers (RFBs) are a proven conservation practice that effectively manage this problem, though adoption rates are low.
A mail survey was conducted to determine differences between adopter and nonadopter characteristics and attitudes with regard
to the use of RFBs. Data were collected from 48 RFB adopters and 261 RFB nonadopters in two Nebraska watersheds. Inferential
and multivariate statistics were used to identify differences between adopter status and producer status groups. About half
(50.8%) the respondents were nonproducers. Nonproducers are agricultural landowners not farming that make decisions about
whether to install conservation practices on their land. Among the adopter respondents, non-farming agricultural landowners
(nonproducers, n=25) were as likely to adopt RFBs as producers (n=23). Adopters were more informed about RFBs and willing
to accept government payments. Receiving technical and financial assistance was a major key to adoption. The research has
identified important opportunities for more effective and targeted RFB extension education programming. 相似文献
