Common diseases and pests of Torreya grandis and their control techniques
Torreya grandis had high application,its main diseases and pests were investigated.The control strategies of agricultural control,physical control,chemical control,and biological control were put forward.Diseases mainly included Erwinia carotovora,Helicobasidium compacum,Endothia parasitia,and Pythium ultinum,etc.Insect pests mainly included Isoptera,Orthoptera,Homoptera,Hemiptera,Coleoptera,and lepidoptera.Isoptera diseases included Odontotermes ormosanus and Macrotermes barneyi of termite family.The pests of Orthoptera included Atractomorpha sinensis and Gryllotalpa orientalis of Gryllotalpa.Homoptera pests included Geisha distinctissima,Dictyophara sinica and Cicadella viridis.Hemiptera pests included Physopelta gutta,Erthesina fullo,and Macrolygus torreyae;Coleoptera pests included Apriena germari;Lepidoptera pests included Lepteucosma torreyae.To reduce the impact of diseases and pests on the growth of Torreya grandis,corresponding control measures should be taken according to the actual situation of diseases and pests,including agricultural measures such as selection of disease-resistant varieties,cleaning weeds and water management,physical measures such as white agent and insecticidal lamp,the chemical measures of using pesticides such as methylthiophanate,carbendazim,and benomyl urea,and the biological measures of introducing natural enemies such as spiders,ladybugs,and hummingbirds.In Torreya grandis diseases and pests control,attention should be paid to reasonable selection of control measures to achieve comprehensive improvement of Torreya grandis pests control effects.The research results provide references for the diseases and pests control and efficient use of Torreya grandis.
