How to deal with diseases of peanut seeds

Peanut main diseases stem rot, root rot, crown rot , blight , etc., yield losses due to these diseases is about 20 % -25% , disease prevention and control better approach is systemic fungicide carbendazim seed treatment . China's production of carbendazim 50% and 40% carbendazim WP Carbendazim colloidal suspension agent , the drug treatment of seeds , the seeds can not only eliminate the bacteria inside and outside , but also can protect the peanut seeds , shoots , roots , stem base from soil bacteria infection , as well as some fertilizer effect. Carbendazim gum disease prevention is better than a suspending agent can be of carbendazim wettable powder .

Chemical treatment methods peanut seeds are the following:

First, the drug soil seed : with 50 % carbendazim WP per 50 kg seeds medicine 0.15-0.25 kg ( calculated as the effective ingredient 0.075-0.125 kg ) , the fine powder with 2.5-5 kg dry soil mix even with medicine soil . Peanut seeds wet washing with water , and then layered soil mixing with drugs , to make each and peanut seeds are evenly coated with drugs soil, soil mixed with drugs immediately after planting.

Second, the liquid seed dressing : with 50% carbendazim WP , per 50 kilograms of peanut seeds with medicine 0.15-0.25 kg , add water 2 kg dubbed liquid,backpack weed sprayers  spray with a sprayer peanut seeds respectively , so that each piece peanut seeds are evenly coated with liquid, dry immediately after planting.

Third, the soaking liquid : with 50 % carbendazim WP per 50 kg seeds with medicine 0.15-0.25 kg , add water to 30 kg dubbed liquid, soak peanut seeds 50 kg , cold soak for 24 hours, turning two middle -3 times , can be planted after soaking .

The prevention of the above methods stem rot , blight, root rot results are above 90%, dressing and soaking no significant difference in the effect of disease prevention , but considering the dressing method is simple, or as seed for the good . Pharmaceutical treatment of peanut leaves dark green , robust growth , with an average increase of about 30%, some 50% of production , or even more than doubled, also at least about 10% yield , pod increased 10-20 % , with the increase of the number of drug the amount of the increase , but the amount of medication ( active ingredient ) than 1% of the seed phytotoxicity , emergence effect .

Although peanut seeds treated with carbendazim significantly increase yield and disease prevention , but this did not wilt agents on disease prevention effects of peanut . No use of carbendazim on the incidence of peanut seeds treated plots , if necessary, can also be hand held sprayer sprayed with a 1000 -fold in the seedling stage liquid, preventing effect is also more than 90 percent , an increase of 10% or more, with 500 times the liquid IRRIGATING there certain effects.
