They were relatively less sensitive to chlorthalonil,metalaxyl,iprodione with an EC50 value of 263.68 μg·mL-1,443.33 μg·mL-1,605.44 μg·mL-1.The result showed that procymidone was very effective preventing Alternaria solani Sorauer in these fungicides.
Theeffect of pollutant concentration, absorbed dose, influence of pH, synergistic effect ofradiation (adding H2O2 and TiO2 in the solution), the impurity (like salts in solvents) inexistence, synergistic degradation with other fungicides were discussed in this paper.
Mutants of nonpathogenic Fusarium oxysporum with altered resistance tofungicides were isolated by using ultraviolet light(230~265 nm)mutagenesis on PDA plate. Resistance to fungicides of 52 mutants and their wild strain 316 were determined according tothe growth rate on PDA with 1μl a.
The preparation is compatible with insecticides (carbofos, vismetrin, talstar, and applaud) and certain fungicides (such as baitan).
The preparation may serve as an alternative to chemical fungicides for plant protection.
Aminoalkylphosphinates Are New Effective Inhibitors of Melanogenesis and Fungicides
Determination of the Optical Purity of Fungicides of the Triazole Series
The influence of the nature of the chiral selector and the composition of the mobile phase on the enantioselectivity of the separation of two fungicides of the triazole series by high-performance liquid chromatography was studied.
Citrus red mite, Panonychus citri McGregor, was reared at the constant temperature Of 25℃,and their egg, larva, nymph and adult were treated with the fungicides of bordeaux mixture (BM) and calcium polysulphides (CP), respectively. The laboratory population parameters of citrus red mite, namely average oviposition per female (E♀), net reproductive rate (R0), mean generation time (T), innate capacity for increase (rm), finite rate of increase (λ) and doubling time (DT) were calculated based on the life...
Citrus red mite, Panonychus citri McGregor, was reared at the constant temperature Of 25℃,and their egg, larva, nymph and adult were treated with the fungicides of bordeaux mixture (BM) and calcium polysulphides (CP), respectively. The laboratory population parameters of citrus red mite, namely average oviposition per female (E♀), net reproductive rate (R0), mean generation time (T), innate capacity for increase (rm), finite rate of increase (λ) and doubling time (DT) were calculated based on the life and fertility table data. The result showed that both BM and CP had certain controlling effects on the population of citrus red mite, and the effect of the latter was better than that of the former.
In this paper some charaters of Botrytis cinerea resistance to three group of fungicides, benzimidazole,dicarboximides and N-phenylcarbamates,were reviewed.The mechanism and the related biological characteristics of resistant is clates of Botrytis cinerea were briefly introducesd
The difference in sensitivity of wheat powdery mildew to triadimefon was compared with detached leaftip method,whole plant method,test-tube method, and bait plant method,and the sensitivity baseline was established. As a result the strain resistant to this agent was found.The results of our study will provide a reference for testing the fungicide resistance of wheat powdery mildew.
