Dressing method is the pharmaceutical and seed evenly mixed together , so that the seed surface covered with a layer of powder or emulsion , for the control of soil pests , insects and seed-borne diseases seedling method of application . This method is suitable for dusts, wettable powders, emulsifiable concentrates , liquid dosage forms , with high efficiency, good control effect , no effect on the natural enemies , without water restrictions, etc. . In powder dressing , can be placed on pesticides and seed dressing , or other apparatus within the uniform mixing . With wettable powders, emulsifiable concentrates or aqueous dressing should press with a good proportion of dilution liquid, then spray the liquid spray to the seed , while spraying edge mix . After dressing , preferably 2 to 3 days pile boring , so that agents are sufficiently adsorbed seeds , pesticides due performance in order to play .

Dipping method .

Dipping method is to pesticides diluted with water , put the seeds or seedlings soaked in liquid , that the seed and seedling absorption and adhesion some agents, for the control of pests and diseases , and promote seedling root bud development . This method is suitable for cream, liquid, wettable powder formulations , with flower workers less seedling effect, with less pesticides and other advantages.

Fumigation method .

Fumigation method is to smoke or ignite fuming fuming original drug to direct heat application methods of pest control .
