Sprayer dispensing needs attention

Now a lot of friends of farmers spraying herbicides are not alone in the preparation of dilutions, but directly to the herbicide added electric sprayer, electric sprayer tank in preparation dilutions, with a good directly after spraying. However, due to the technical preparation of the herbicide master well diluent, in the preparation process tends to occur, which directly affect the herbicidal effect. In order to improve the control effect of herbicides in the dispensing process must pay attention to the following four questions:
1 herbicide formulations
There are many formulations of herbicides with different formulations prepared in different ways. Such as emulsions, liquid and gel suspension agent will quickly dissolve after water and spread of these formulations can be further dilution method herbicide formulated about a certain amount of herbicide directly into the nebulizer dilute garden sprayers immediately after good Shi. 72% Doyle emulsion, 90% Wo Nice EC can use this method. Wettable powders, dry suspension emulsion and other formulations step dilution method can not be used, but must be prepared using the two-step dilution method: The first step is accurately weighed on demand herbicides, add a little water stir, it is fully dissolved liquor. The second step is to add a certain amount of mother liquor certain amount of water, diluted to spray evenly. 75% superstar hanging drying emulsion, 25% WP nitrofen and so must be diluted using this method, and must not be a one-step dilution dilution.
(2) preparation of diluent
In the medicine cabinet in the preparation of electric bottle sprayer diluent, you must first kits add about 10 cm deep water only after the mother liquor was added slowly to the pharmacy or medicine cabinet, and then add water to the water line can be sprayed. Never add water in the water tank before or will not fill with water and pour it into the tank agents or liquor, because it is difficult to prepare a homogeneous diluent, will seriously affect the control effect.
3 with a good liquid medicine chest immediately after spraying
The reason is the proportion of various herbicides and not exactly the same proportion of water, such as herbicides gravity than water, stored herbicide will sink over time, resulting in lower liquid concentration, the upper liquid concentration is small, serious impact on weeding results.
4 electric sprayer in the dilution was added to the water line of electric sprayer as well
Electric sprayer in the spray dilution was added to the water line as well, must not be filled at once. If the medicine chest full of electric sprayer, spraying personnel in the liquid medicine chest when walking is difficult to shake, Pharmacy prone to sinking or floating phenomenon, affecting the uniformity of the liquid, thus affecting the herbicidal effect. In addition, the application personnel also easy when spraying liquid spilled out from the medicine chest catchy, drip application personnel to the body, so the medicine cabinet in the liquid must not overfill.
