The effect of muskmelon tolerance on some herbicides

In order the examine the effect of muskmelon tolerance on some of herbicides, a field experiment was conducted in spring of 2009 in Saveh farmland, Iran. The Experiment was conducted by using a randomized complete block design with three replications and applying 13 treatments. The following herbicides were examined: sonalan, basagran, stomp, goal, basagran+gallant super,treflan, sonalan+gallant super, nicosulfuron+gallant super, eradicane, goal+gallant super, nicosulfuron, treflan+gallant super and gallantsuper. All herbicide treatments were applied at the rate of recommended. Herbicide injury score (0 to 100) were recorded at one & two weeks after application of herbicides.The results showed that the lowest injury occurred by treflan, sonalan & stomp with 4.1, 7.5 & 12.5 percent, respectively and maximum injury occured by goal, eradican, nicosulfuron & basagran. All plants were destroyed by eradiction treatment. Overall, three pre-planting herbicides (treflan, sonalan & stomp) are recommend for muskmelon cultivation.
