Influence of weather factors on the incidence and distribution of leaf miner infesting ridge gourd

Abstract

The present study was carried out on the influence of weather factors on the incidence and distribution of leaf miner infesting ridge gourd during kharif season of 2017 at the Central Experimental Station, Wakawali, Dist. Ratnagiri. The results revealed that there were marked differences in infestation of leaf miner. The infestation of leaf miner (0.04 ± 0.26) was started in the 28th SMW (09 - 15 July). Minimum leaf miner infestation (0.04 ± 0.26) was recorded in 28th SMW (09 - 15 July) and 29th SMW (16 - 22 July), while maximum (0.84 ± 0.26) infestation was noticed during 33rd SMW (13 - 19 August). The data on the correlation between mean infestation of leaf miner with different meteorological parameters found to be non significant.
