Abstract:

Egyptian broomrape (Orobanche aegyptiaca Pers.) is the most troublesome root holoparasitic weed which causes severe damage to tomato and brinjal crops grown in Mewat and Bhiwani areas of Haryana. A study was conducted to test the efficacy and selectivity of two sulfonylurea herbicides, viz. sulfosulfuron and ethoxysulfuron, and neem cake; pendimethalin in combination with metalaxyl along with sulfonylurea herbicides for managing O. aegyptiaca in tomato and brinjal in field conditions. The post-emergence application (PoE) of sulfosulfuron and ethoxysulfuron at 50 g/ha 30, 60, 90 DAP (days after planting) were more selective to tomato and to control the parasite, O. aegyptiaca, more effectively with average yield increase of 51.7% over untreated check. Neem cake or metalaxyl were not effective to inhibit the growth of O. aegyptiaca in brinjal. It is inferred from this study that ethoxysulfuron at 25 g/ha PoE at 30 DAP and at 50 g/ha or sulfosulfuron at 50 g/ha PoE at 30 and 60 DAP, provided 85-90% control of O. aegyptiaca in tomato. Both the herbicides caused phytotoxicity to brinjal. The results of eight adaptive on-farm trials conducted in tomato during 2016-17 also revealed 92.3% control of O. aegyptiaca with a yield increase of 30.8% over untreated control.
