摘 要:分别于柑桔嫩梢期、幼果期和果实膨大期应用炔螨特、三唑锡和三磷锡3种杀螨剂进行药害试验,并在药后不同时期进行调查,结果证实3种杀螨剂均对春梢嫩叶有不同程度药害,20%三磷锡EC对锦橙叶片的药害最重,600倍液可造成部分叶片脱落.在果实上使用炔螨特浓度过高会造成'花果'现象,25%三唑锡可湿性粉剂1500~2000倍液对锦橙和温州蜜柑果实无药害,7月中旬施用三磷锡500倍对果实有药害,1000~2000倍比较安全.The experiments were done with spraying propargite,azocyclotin,phostin on citrus in the citrus current shoot period,young fruit period,fruit expanding period.The results indicated that3acaricides do harm to citrus spring cycle shoot on different level.Phostin was the most seriousone to Glorious orange Leaves,its600times could make part leaves fall.Propargite could cause fruit mottled with h igh concentration.Azocyclotin25%WP1500~2000times do harmLess to Glorious orange and Unzhu mikan.In mi d dle july citrus fruits were damaged using azocyclotin500times,It were safe using1000~2000times.
