Abstract:

A forecast model of wheat basal rot was established with in this paper using a method for synthetic decision of Fuzzy Mathematics. The incidence was predicted value. The prognostic factors had time of sowing, accumulated temperature was higher than 0℃ in November, accumulated temperature of January to February, accumulated temperature that the first twenty days of a month March, and rainfall in March. Fungicide treatment results showed that the control effects of thiophanate-methyl 50% WP, carbendazim 25% WP and benomyl 50% WP were all above seventy-five percent when the treatment time in disease primary.
