【摘要】 猕猴桃(Kiwifruit)软腐病是由Botryosphaeri asp.和Phomopsis sp.两种病原菌侵染造成的。病菌以菌丝体、分生孢子和子囊壳在枯枝、果梗上越冬,越冬后的菌丝体分生孢子器至翌年春恢复活动,4—6月生成孢子,成为初侵染源,6—8月大量散发。通过室内药效测定和野外药剂防治猕猴桃软腐病的试验表明,药效依次是多菌灵、抗菌素402、退菌特、抗菌素401、波尔多液。更多还原

【Abstract】 The soft rot of Kiwifruit pathogen was caused by Botryosphaeria sp.and Phomopsis sp.which over wintered as mycelium,conidia and perithecium in the dead branches and fruit stalk.Mycelium and pycnidium reactivated after winter,formed spore from 4-6 months and became initial infective source.This spores spreaded abundant from 6-8 months.Chemical control measures on the soft rot of Kiwifruit were estabished by insecticide efficacy determination and field experiments.The results indicated that the chenicals in order of control effects were Carbendazim>Antibiotic 402>Tuzet>Antibiotic 401>Bordeaux mixture.更多还原
