Abstract
Over the last two decades in response to rising production costs in many Asian countries the method of establishing rice by manual seedling transplantation has changed to direct cultivation. Changing the method of rice establishment and the resulting stresses has led to pay more attention to management methods in direct rice cultivation. Rice stem borer (Chilo suppressalis) is one of the most destructive pests of this product. In this study, the efficacy of Hexaflumuron (Consult®) and Kitoagrosens inhibitor fertilizer with the recommended concentrations  was evaluated to control this pest at intervals of 3, 7, 14 and 21 days after spraying using Henderson-Tilton method. Their effects on rice yield components were investigated, too. The results showed that in terms of insecticidal efficacy on rice stem borer, both the compounds were most effective after 7 days, while Hexaflumuron ( >90%) was more effective than Kitoagrosens (~70%). On the other hand, the results related to crop yield components showed that Kitoagrosens had better effects on all parameters, especially on 100-seed weight, which is significantly higher than other treatments. Based on the results of this study, it can be concluded that Kitoagrosens has e less insecticidal ability than Hexaflumuron but have a greater strengthening effect on the quantitative and qualitative indicators of rice crop.
