1 Inhibitory Experiment of Chlorothalonil and its fluorine containing derivative against oryzae were carried out.

2 The analysis of chlorothalonil and procymidone by GC was introduced.

3 A method for determination of chlorothalonil in the aerosol by capillary gas chromatography was described.

4 The effects of repeated chlorothalonil treatments on soil enzyme activities were similar to those on soil microbes.

5 The degradation trends of cypermethrin, fenvalerate, chlorpyrifos and chlorothalonil in autumn spinach were studied under open-field condition by spraying.

6 A detection method for determination of chlorothalonil residue in environmental water samples by single drop microextraction(SDME)-reverse phase liquid chromatography(RPLC) has been studied.

7 Experiments showed Chlorothalonil and Bordeaux mixture were effective fortheir control.

8 Objective: To study the method of determination of chlorothalonil residues in vegetables.

9 Under HPML and sunlight,(www.Sentencedict.com) chlorothalonil had a higher photolysis rate in alkaline solution than in neutral and acid solution.

10 The production principle of chlorothalonil, cof waste gas and treatment situation were analyzed. Comprehensive treatment of was te gases containing cyanogen and chlorine were put forward.

11 GC-ECD was used to study the change of chlorothalonil WP(75%)residue in cucumber and tomato before and after their processing.

12 For water-soluble pesticides such as chlorothalonil, cleaning effect was positive, but was not evident for organic phosphorus pesticides.

13 Inhibition of 10% Score to the hyphe growth(76.5%)and spore germination(54.4%)was obvious for B cinerea, the second was Chlorothalonil(60.6 and 50.7%).

14 The protective fungicide is at least one of zineb, propineb, thioneb, thiram and chlorothalonil.

15 Prescription for the powdery of double efficient and waterish 70% of chlorothalonil was studied by screening of auxiliary regents and carriers.
