ACTIVITY - Fungicide; Plant protectant; Insecticide; Antibacterial. The efficacy of 2-(difluoromethyl)-N-(2-ethyl-1,1-dimethyl-2,3-dihydro-1H-inden-4-yl)-5-methylnicotinamide (I'a) was evaluated in vivo preventive test on Uromyces appendiculatus (bean rust). The contaminated bean plants are incubated for 24 hours at 20 degrees C and at 100% relative humidity, and then for 10 days at 20 degrees C and at 70-80% relative humidity. The compound (I'a) showed grading (% of efficacy) of 100%.    MECHANISM OF ACTION - None given.    ADMINISTRATION - The difluoromethyl-nicotinic indanyl carboxamide compound is applied at application rate of 0.1-10000 gram/hectare (g/ha), preferably 10-1000 g/ha, especially 10-800 g/ha, particularly 50-300 g/ha by watering, dripping, spraying, or injection.    SPECIFIC COMPOUNDS - 100 Compounds are disclosed as the compound (I) e.g. 2-(difluoromethyl)-N-(2-ethyl-1,1-dimethyl-2,3-dihydro-1H-inden-4-yl)-5-methylnicotinamide (I'a), 2-(difluoromethyl)-N-(2-ethyl-1,1-dimethyl-2,3-dihydro-1H-inden-4-yl)-5-methylpyridine-3-carbothioamide, 2-difluoromethyl-N-(1,2-dimethyl-indan-4-yl)-nicotinamide, 2-difluoromethyl-N-(2-ethyl-1,1-dimethyl-indan-4-yl)-nicotinamide, 2-difluoromethyl-N-(1,1,2,3-tetramethyl-indan-4-yl)-nicotinamide.    EXAMPLE - In a microwave sealable tube, 0.94 ml propanephosphonic anhydride was added to 118 mg a solution of 2-(difluoromethyl)-5-methylnicotinic acid and 100 mg 2-ethyl-1,1-dimethylindan-4-amine in 10 ml tetrahydrofuran (THF). The tube was sealed and the reaction was microwaved for 10 minutes at 150 degrees C.
