E-type camphene aldehyde oxime is synthesized by the reaction of E-type camphene aldehyde with hydroxylamine hydrochloride under the action of sodium carbonate.E-type camphene aldehyde oxime is dehydrated with acetic anhydride to obtain E-type camphene nitrile.The yield and purity of the product are over 90%.The structures of the products are characterized by MS and NMR.The inhibitory activity of E-type camphene aldoxime and camphene nitrile on the growth of 12 plant pathogenic fungi is tested by mycelial growth rate method.The results show that under the concentration of 500 mg?L-1,the inhibition rate of E-camphene aldoxime on GlomerellaCingulata(A),Gibberellazeae(B),Alternariakikuchiana(C),Sclerotiniasclerotiorum(D)and Thanatephoruscucumeris(E),Phytophthoracapsici(F),Ceratosphaeriaphyllostachydis(G),Botryisphariadothide(H),Colletotrichumgloeosporioides(K)all reach 100%.The inhibition rate of E-type camphene nitrile on plant pathogenic fungi is higher than 98.5%,most of which are 100%.When the concentration of the solution is 250 mg?L-1,the inhibition rate of E-camphene aldoxime to 7 plant pathogenic fungi,such as A,B,E,F,G,H,K is still more than 95%.The inhibition rate of 2 compounds exceeds or even far exceeds that of chlorothalonil
