Abstract

Pathological fruit drop in citrus is a wide spread disease in Punjab and results in huge economic losses to Kinnow mandarin growers. The disease was significantly higher during second fortnight of September and first fortnight of October in Fazilka, Hoshiarpur and Ludhiana districts of Punjab. Two fungal pathogens viz. Colletotrichum gloeosporioides and Diplodia natalensis were found to be associated with the fruit drop disease. Among the systemic fungicides, thiophanate methyl (25ppm), tebuconazole (50ppm) and difenconazole (50ppm) resulted in complete inhibition of mycelial growth of C. gloeosporioides and D. natalensis. Copper hydroxide (200ppm) and zinc dimethyl dithiocarbamate (200ppm) were found to be the most effective non-systemic fungicides in completely (100%) checking the growth of pathogens.
