Abstract | ||
Three natural materials were used as additives (capsicum, garlic and boiled linseed oil) to profenofos for improving its efficiency against adult stage of whitefly, Bemisia tabaci and aphids, Aphis gossypii on leaves of squash plant under field conditions. Each additive was used alone at the concentrations of 1.5, 2.5 and 3.5 %. The concentration of 2.5 % of each additive was also applied in combination with the half recommended field rate of profenofos. All treatments were compared to profenofos at the recommended rate (750 ml in 200 liters of water / feddan) and its half rate as well as to the untreated check. Two experiments were carried out on August and November months (2005), with mentioned treatments. Data indicated that the combination of natural materials with profenofos concentration (2.5 %), their mixed with half recommended rate of profenofos, achieved excellent efficiency for controlling whitefly and aphids, and obtainable initial effect > 70 % and > 40 % as residual effect, respectively. On the other hand, their effectiveness achieved equal, slightly higher or less than the insecticide when used at the recommended rate. Repeated use of 1.5 % of capsicum or garlic offered valuable efficiency more than the half recommended rate of profenofos against the two tested insects. Generally, boiled linseed oil was less efficient and reachable < 70 % and < 40 % as initial and residual effect, respectively. | ||
