在甘蔗分蘖期施放棵棵无损5％颗粒剂和呋喃丹3％颗粒剂，探讨这2种农药防治甘蔗害虫的效果及对蔗茎产量的影响。试验结果表明：对甘蔗螟虫的防效，棵棵无损和呋喃丹不相上下；对甘蔗蓟马、绵蚜虫的防效，棵棵无损明显好于呋喃丹。对蔗茎产量和经济效益的影响，棵棵无损比对照增产极显著，产量增长15．1％，效益增长13．7％；较呋喃丹增产显著，产量增长10．4％，效益增长12．0％。呋喃丹比对照略有增产，但效果达不到显著水平。棵棵无损除了对甘蔗害虫具有良好的防效而使产量损失减少外，由于该药剂在配方中添加了一种特有的高分子助剂，能促进甘蔗生长，显著地增加蔗茎产量。

Two pesticides, 5% ＂Kekewusun＂ Granule and 3% Furadan Granule, were applied at early tillering stage to study the effect on the control of sugarcane pests and on cane yields. The results showed that they were of approximately the same effect to control sugarcane borers, but ＂Kekewustm＂ Granule was obviously superior to control sugarcane thrips （Fulmekiola serratus （Kobus））, sugarcane wooly aphis （Ceratovacuna lanigera （Zehntner））, and improve cane yields, compared with 3% Furadan Granule. Cane yields and economic benefits of ＂Kekewusun＂ Granule were increased by 15.1%, 13.7% respectively than that of the CK, and by10.4% and 12.0% respectively than that of Furadan Granule. In addition, 5% ＂Kekewusun＂ Granule can also promote sugarcane growth and significantly increase cane yields due to its special polymer additives.
