chinois. 在保护地用98％棉隆微粒剂、5％硫线磷颗粒剂、10％噻唑膦颗粒剂处理土壤，防治黄瓜和番茄上根结线虫试验结果表明，3种药剂均可有效地控制根结线虫的危害。在番茄地3种处理的病指分别为27．6、41．3和46．7，增产率分别为77．9％、63．8％和52．8％，空白对照病指达100。在黄瓜地3种处理病指分别为2．69、3．49和9．11，增产率分别为56．6％、45．3和44．2％，空白对照病指为31．11，差异极显著。[著者文摘]
Afficher plus [+] Moins [-]anglais. 98% Dazomet MG, 50% cadusafos GR and 10% fosthiazate GR were respectively mixed with soils to control the root-knot nematode on cucumber and tomato in greenhouses. The results showed that these chemicals had good efficacy to suppress damage of nematode In tomato fields treated with dazomet, cadusafos and fosthiazate, disease index was 27. 6, 41. 3 and 46. 7, while in control plots it was 100. The yield of tomato in these three treatments increased by 77. 9%, 63. 8% and 52. 8%, respectively. Disease index on cucumber fields was 2.69, 3. 49 and 9.11, significantly different from the control （31.11）. The yield of cucumber increased by 56. 6%, 45. 3% and 44. 2%, respectively.
