5种杀菌剂对油橄榄叶枯病菌的毒力测定及对病害的田间防效评价
Evaluation of the Virulence Determination of Five Fungicides against Phomopis olea-europaea and Field Efficacy in Disease Control
摘要
Abstract
Using the mycelial growth rate method,the inhibitory effects of five fungicides,including chlorothalonil,mancozeb,difenoconazole,thiophanate-methyl,and pyraclostrobin on P.olea-eu-ropaea were determined in laboratory conditions.A protective trial of these five fungicides against P.olea-europaea was conducted on detached leaves of 2a olive trees.The fungicides that exhibited strong inhibitory and protective effects were selected for field trials to assess their efficacy in control-ling the disease.The results indicated that all five fungicides had,to some degree,inhibitory and pro-tective effects against P.olea-europaea significantly,pyraclostrobin and difenoconazole stood out as highly effective in suppressing the pathogen and protecting the plant.After harvesting the olives,it is recommended to timely remove disease-infected branches and fallen leaves from the olive orchard.Apply Bordeaux mixture twice,with an interval of 10-15 days,as a basic preventive measure to e-liminate overwintering pathogens.In the following year,when new leaves emerge on the olive trees,apply either 25％pyraclostrobin at a dilution of 1∶1 000 or 37％difenoconazole at a dilution of 1∶1400 twice,with an interval of 7-10 days,to effectively control the disease.This treatment protocol can effectively reduce the spread and infection of P.olea-europaea,demonstrating significant control efficacy against the disease.关键词
