Studies On The Experiment Of Plain Stone Of The Garlic And Fragrant Ru Volatile Oil On Prevention And Cure Effects On Tomato Disease

In recent years, because warm damp condition and environmental terms suitable for and person who act as factor in succession year after year, cause our country and our province tomato disease to take place seriously. Use the single , high-efficient but hypertoxic , high chemical agriculture chemical that remain in a large amount for a long time at the same time, causing the tomato quality in our province to drop, the residues of pesticides amount is high, the domestic competitiveness is reduced, have already become the main factor of influencing tomato development of our province at present.Since entering the eighties of the 20th century, developing direction that the numerous scientists of the world regard looking for high-efficient , low toxicity , low residue and harmonious environment-friendly agriculture chemical of environment as the agriculture chemical and research and develop. Test this select garlic plain , stone fragrant Ru volatile oil two plant source environment-friendly drug for use, restrain the fungus to test and test with the field drug effect to pathogens of main disease of the tomato in the room, determine the plain volatile oil of garlics , restraining the fungus result indoors of fragrant Ru volatile oil of stone, have defined that prevents and cures the result in these two kinds of drug the main disease of the tomato - tomato gray mold and field of the early epidemic disease of tomato to revealing , have probed into and gushed out and constructed the impact on such respects as the shape of the tomato , fruit quality , etc. after these two kinds of drug of fragrant Ru volatile oil of plain volatile oil of garlics , stone. Have drawn the following conclusion:First, Restraining the result of the test of fungus in the room indicates, in 2000, 4000, 6000, 7000, in the 8000 , 9000 , 10000 , 20000 - 30000 9 density gradients, the garlic is plain , two kinds of environment-friendly drug of volatile oil of Ru have certain inhibition on withered ill, early epidemic disease of the tomato, leaf mildew, pathogen of the gray mold on the stone is fragrant. Garlic plain among them, stone fragrant Ru volatile oil 2000 liquid suppress result to be remarkable to tomato gray mold fungus , tomato withered germ , tomato early epidemic disease germ, it is 98 respectively. 89% and 99. 12% (garlic plain , stone fragrant Ru volatile oil , same below ) , 99. 03% and 99. 47%, 80. 00% and 76. 00%; Two drug dilutes and can play a certain restrain arrivesing role to 4 above-mentioned germs once 30000 times of liquid . Second, The result of the test of field shows , garlic plain volatile oil 500-1500 and stone fragrant Ru volatile oil 600-1000 is it have better prevention and cure result in field to tomato early epidemic disease and tomato gray mold to deal with each. Garlic plain volatile oil 500 liquid and stone fragrant Ru volatile oil 600 liquid is it prevent and cure result to be best to tomato early epidemic disease and tomato gray mold to deal with among them, it is 93 respectively to defend the result in 14 days after the second medicine. 96%, 93. 68% (early epidemic disease ) and 94. 14%, 91. 38% (gray mold), higher than contrast drug 75% hundred fungus clear prevention and cure result of WP notably, variance analysis results indicate, in P =0.01 levels make the difference remarkably.Finally, compared with the contrast, the garlic and volatile oil of Mosla chinensis scarcely influence the tomato forms including height, width, stem diameter, and tomato quality including careless shape thing of solubility, soluble candy, organic acid, Vitamin C. Therefore, it showed that the garlic and volatile oil of Mosla chinensisdid not afect the normal growthof tomato.
