Abstract
An experiment was conducted at Junagadh during rabi season of 2012–13 to find out the effect of herbicide mixture and phytotoxic effect of herbicide on onion crop. Application of pendimethalin @ 0.900 kg ha−1 as PE followed by imazethapyr @ 0.050 kg ha−1 as POE at 45 DAT significantly reduced the population of weeds and higher weed control efficiency after weed free check followed by combined spray of oxyfluorfen @ 0.240 kg ha−1 and propaquizafop @ 0.090 kg ha−1 as PE & second spray as POE at 45 DAT. However, this treatment has higher weed index and lower bulb yield over rest of the treatments. Application of imazethapyr @ 0.050 kg ha−1 as POE showed up to 80% phytotoxic effect on onion. The lowest weed index and the highest bulb yield was obtained under combined spray of oxyfluorfen @ 0.240 kg ha−1 and propaquizafop @ 0.090 kg ha−1 as PE & second spray as POE at 45 DAT after weed free.
