The invention discloses an application method for controlling cotton
verticillium wilt by utilizing
terbinafine to target
verticillium dahliae
sterol binding protein VdPBP1, and relates to the technical field of cotton control, and the method comprises the following application steps: S1, confirming the characteristics of a
terbinafine medicament; s2, formulating a
terbinafine application scheme; and S3,
verification and guarantee of prevention and control effects. According to the method, theoretical support is provided for precise prevention and control; the EC50 of the terbinafine is 10.8 ng / mL, the dosage of the medicament can be greatly reduced, the monovalence of the terbinafine is 30.4 yuan / g, so that the large-scale application cost is lower, the terbinafine is only combined with
verticillium dahliae VdPBP1 and blocks mediated
electron transfer of the
verticillium dahliae VdPBP1, and the existing medicaments such as phenazino-1-
carboxylic acid can inhibit
histone acetylation and
benomyl has wide action targets of interfering microtubulin, so that the application range of the medicament is widened. Non-target organisms are easily influenced; moreover, an
ergosterol synthesis pathway is an essential pathway for fungi, and the VdERG1 is a
single copy gene in
verticillium dahliae, so that
pathogenic bacteria are difficult to generate
drug resistance through
gene mutation, and prevention and control nodes widely cover the whole growth period.
