مطالعه کارایی چند ترکیب حشره کش برای کنترل سن‌های زیان اور پسته

The bed bugs are one of the most important pests in pistachio orchards. The damage of the pest from the stage of fruit formation to the hardening of the bone skin causes the whole fruit to turn black at the beginning of the season. Chemical methods are now being used to control these ages and prevent them from being damaged. In order to diversify the registered compounds against the pistachio age pest, thiacloprid insecticide with the trade name Biscaia® was evaluated in comparison with two common insecticides. In order to diversify the registered insecticide for control of pistachio bugs, tiachloprid (Biscaya) was evaluated in comparison with two common insecticides namely, Eforia® and finitrition. This project was carried out in 3 provinces: Kerman, Khorasan Razavi and Yazd with 4 replicates and 5 treatments in using randomized complete design. The treatments were tiachloprid (Biscaya® with doses 0.4 and 0.5 /1000), Eforia® (0.4/1000), finitrition (1.5 /1000) and control (water). The number of nymphs was counted on 32 leaves of each plot before and and 7 days after spraying. The number of seeds of pistachio damaged by bugs counted on four clusters of two trees, in three dates after spraying in each plot. In seven days after spraying, the efficaccy percentage for treatments were 89.87, 85.31, 89.11, and 66.65 repectively, and the mean number of seeds of pistachio damaged were 8.35, 8.75, 8.74, 10.87% respectively. It was estimated at 30.7% for control. The results showed that tiachloprid (0.4/1000) has 85.31% control of bugs and this treatment was an effective insecticide for controlling the Pistachio bugs and can be used in control programs.
