Sunn is one of the major pests of wheat in the fertile age in most provinces there in wheat and barley and wheat affect their enormous losses annually. The aim of this study was to evaluate the efficiency of commercial formulation of deltamethrin (two forms of EC and SC) production in the Age of wheat. 10 business deltamethrin was prepared from 9 manufacturers.
An experiment with 12 treatments and four replications in a tropical area (Buin Zahra) and cold (Koohin) in a randomized complete block design.
Treatments consisted of 9 2/5 % EC deltamethrin formulations at concentrations of 300 ml per hectare of companies PR, GL, MS, BY, GA, SM, BH, AY, KV and a type of deltamethrin formulations 2/5 % SC with two concentrations of 400 and 300 ml per hectare of KV, against age and nymphs were used on infected farms wheat. Field experiments to compare the performance of different insecticides on the age of the mother in a tropical area showed that all treatments had acceptable performance but there is a significant difference between treatments (0/0001 >P).
Most losses in terms of performance on the age of the mother at 5 and 10 days after treatment (91/32 and 78/35 percent, respectively) and lowest impact on the Company KV times cited, related to the GAE. Test results also insecticides on nymphs of Sunn pest in tropical and cold at 5 and 10 days after treatment showed
The percentage performance of all treatments at 10 days after treatment every 2 area is more than 5 days after spraying and the percentage of SC in the third stage of formulation performance is higher than the EC formulation.
In between treatments KV in the third stage had the highest percentage of efficiency.
