Beet cyst nematode is most important parasitic nematode and subject of studies on a century. Transferring resistance from different sources to sugar beet cultivars was subject of the study. Wild species of Beta genus including Beta maritime,( W-1001, W-1010) and B. procumbens (W-1009) were resistant sources. The mentioned genotypes were crossed to 3 different multigerm (MSR, MSNB1, and MSC2) a ...

The efficacy of Pamizole Super against Fasciola hepatica, gastrointestinal helminths, and Dictocaulus viviparis and that of Distomicida against F. hepatica was studied on 16 naturally infested adult Ethiopian zebu cattle. Experimental animals were divided into two groups of six each plus four control animals, designated as group 1 (Pamizole Super treated), group 2 (Distomicida treated), and gr ...

This research was conducted to evaluate effectiveness of five plant oils (three essential oils (rosemary, thyme, mint) and two plant oils (garlic, sesame)) against root knot nematode (Meloidogyne incognita) in 2006-2009. Trial was designed as randomized complete block design with two different nematode inoculum densities (1000, 2000) J2/pot and two different essential oil concentrations (50, 1 ...

土壤药剂处理结合阳光消毒防治番茄根结线虫技术评价

Zhang Zhuo, Chinese Academy of Agricultural Sciences et al. [jun.2011]

摘  要:为了筛选安全、高效、实用的化学防治技术,对国内外生产的5种杀线虫剂(棉隆、1,3_二氯丙烯・氯化苦、威百亩、噻唑磷、溴甲烷)土壤处理结合阳光消毒防治番茄根结线虫的效果进行了评价。结果表明,使用98%棉隆微粒剂450 kg/hm_2或10%噻唑磷颗粒剂30 kg/hm_2防治番茄根结线虫(_Meloidogyne incognita_),结合夏季高温进行阳光消毒,能有效地降低番茄根结线虫的数量,减轻根结线虫的危害程度,节省农户的生产成本,提高番茄的产量和农户的经济效益,是夏季防治番茄根结线虫的有效措施。

9种杀线剂对香蕉根结线虫病的防效评价

Rui Kai, Hainan Academy of Agricultural Sciences et al. [oct.2011]

摘  要:对9种不同作用机理的杀线虫制剂进行了田间防效评价试验。结果表明,10%噻唑磷颗粒剂、35%威百亩水剂和98%棉隆微粒剂对根结线虫具有良好的防效,不仅能控制土壤中2龄幼虫数量,而且能非常有效地抑制根结的形成,同时具有速效性好、持效期长、残留毒性低等优点,可作为根结线虫防治的首选药剂;5%丁硫克百威颗粒剂和0.5%阿维菌素颗粒剂具有较好的防效,对土壤中2龄幼虫数量和作物根结的形成具有中等水平的控制能力,速效性好、同时具有一定的持效性;生防制剂5亿活孢子/g淡紫拟青霉颗粒剂和2.5亿孢子/g厚孢轮枝菌微粒剂在香蕉生长前期防效较差,而在生长中期的防效逐渐上升并保持稳定;2.5%二硫氰基甲烷可湿性粉剂的表现一般,但可在生长季节多次灌根使用,同时具有毒性低、使用方便的优点,是当前为数不多的、能在作物生长季节里施用的广谱型杀线虫制剂;50%氰氨化钙颗粒剂的表现最差,仅能一定程度地控制根 ...

The impact of different treatments on population of three nematode species associated with guar (Cyamopsis tetragonoloba) and the yield of guar were investigated. The chemical nematicides and plant extracts significantly reduced the population densities of all three nematodes. Carbofuran was most effective against all the nematodes. Apart from other three treatments, Tridax procumbens emerged ...
