Abstract:
Seed treatment with insecticide is necessary to protection of cotton seed from pests. Research was conducted in Randomized Compelet Block Design (RCBD) with 4 replication in 2013-2015 in Gharakhil agricultural research station at Mazandaran province, Ghaemshahr city and Karkandeh research station at Golestan province, Kordkuy city. This research were carried out with treatments included 1-control (no treatment) 2-seed cover with a mixture of cow dung and clay to 50% 3- Neem Azal T/S 1/5 % 4-Gaucho 5-7 gr/kg seed 5-Carboxin-Tiram 7-10 gr/kg seed 6-cover with liquid manure of cow urine. Intra and inter row spacing was 80×20 cm. Results showed that treatment of cotton seed with Gaucho was the best with high product yield and cotton seed emergence than other treatments. Neem Azal T/S was in the next stage in control of Thrips and cutworms. Highest number of aphids was in neem azal treatment and lowest number of aphids was in Liquid manure cow urine. Cow dung has the least effect on damping off and carboxin tiram treatment has the least damaged cotton plants. Use of animal fertilizers and natural ingredients in cotton seed disinfestation will help to reduction of the use of chenichals in pest and diseases of coton.
