| Description |
Trichoderma harzianum is an important biocontrol agent which is being used for the management of many plant diseases. Under integrated management it is being used in combination or alternation with synthetic and non-synthetic chemicals. In present study an effort was made to check the compatibility of Trichoderma harzianum Rifai strain PBAT-21 with fungicides, insecticides and weedicides at the recommended and half of the recommended doses. On the basis of mycelial growth and spore germination zineb, mancozeb, sulphur, kresoximmethyl, azoxystrobin, metalaxyl, cymoxanil+mancozeb, mandipropamid, triademefon, myclobutanil, dimethomorph, mandipropamid+mancozeb, metalaxyl+mancozeb, cymoxanil+ mancozeb, carboxin+thiram, streptocyclin, chitosan at both recommended dose and half of the recommended dose and boric acid and, flutriafol myclobutanil at half of the recommended doses were found to be compatible whereas thiram, dinocap, pyraclostrobin, propiconazole, penflufen, azoxystrobin+flutriafol, pyraclostrobin+metiram and boric acid , flutriafol, myclobutanil at recommended doses were found to be incompatible. On the basis of sporulation azoxystrobin+flutriafol, mandipropamid+mancozeb, carboxin+thiram and streptocyclin at both recommended dose and half of the recommended dose and metalaxyl+mancozeb, chitosan, boric acid, mancozeb, thiram, zineb, kresoxim-methyl, mandipropamid, penflufen, cymoxanil+mancozeb at half of the recommended dose were found to be compatible whereas sulphur, dinocap, flutriafol, pyraclostrobin, azoxystrobin, metalaxyl, myclobutanil, dimethomorph, triademefon, propiconazole, azoxystrobin+flutriafol, pyraclostrobin+metiram at both recommended dose and half of the recommended dose and thiram, zineb, mandipropamid, penflufen, kresoxim-methyl, metalaxyl+mancozeb and cymoxanil+mancozeb at recommended dose were found to be incompatible with T. harzianum Rifai strain PBAT-21. On the basis of mycelial growth and spore germination insecticides like thiamethoxam, imidachlorprid, carbofuran, cartap hydrochloride, chlorantraniliprole was found to be compatible whereas fipronil and chlorpyrifos were found to be incompatible. On the basis of sporulation fipronil at both recommended dose and half of the recommended dose cartap , imidachlorprid and chlorpyrifos at half of the recommended dose and carbofuran, chlorpyrifos, thiamethoxam, cartap hydrochloride, chlorantraniliprole, imidachlorprid at recommended doses were found to be incompatible with T. harzianum Rifai strain PBAT-21. Weedicides like sulfosulfuron, chlorimuron+metsulfuron methyl and imazethapyr was found to be compatible whereas pendimethalin, oxyfluorfen, cladinofop, bisbyribac sodium at both recommended dose and half of the recommended dose were found to be incompatible. On the basis of spore germination sulfosulfuron, chlorimuron+metsulfuron, imazethapyr, ethoxysulfuron, pendimethalin and oxyfluorfen was found to be compatible whereas bisbyribac sodium was found to be incompatible. Sulfosulfuron, imazethapyr and bisbyribac sodium at lower dose were found to be compatible whereas chlorimuron+metsulfuron, ethoxysulfuron, pendimethalin, bisbyribac sodium at recommended dose and oxyfluorfen was found to be incompatible with T. harzianum Rifai strain PBAT-21. Survival was better in sterilized soil than unsterilized soil. The population of Trichoderma harzianum increased in both sterilized and unsterilized soil on treatment with weedicides like bisbyribac sodium, insecticide like thiamethoxam and fungicides like carbendazim, meatlaxyl+mancozeb and pyraclostrobin. |
