It is often asked to use well water to dilute pesticides ? This problem is actually one-sided, because some pesticides can be diluted with well water, and many pesticides can not be diluted with well water, because the well water contains more minerals, such as calcium and magnesium. If well water containing calcium and magnesium is used to dilute emulsifiable pesticides such as dimethoate, marathon, trichlorfon, methamidophos, etc., calcium, magnesium and other substances in the well water are easily combined with the emulsifiable concentrate in the pesticide to produce sediment. Therefore, the emulsification performance of the pesticide is destroyed, and the use effect of the pesticide is reduced.
However, today's pesticide Xiaobian is to say that if the pesticide is diluted with well water, adding a little rice vinegar will have a good effect:
In the introduction of many pesticides, many experts are saying that the dilution of pesticides in well water has a certain effect on its efficacy, but how to add some rice vinegar will have different effects. When dilute the dilute dichlorvos, omethoate, methamidophos and some herbicides with groundwater such as well water and mountain spring water, the minerals such as calcium and magnesium in the water are easily combined with the agent to cause precipitation and destroy the emulsifying properties of the pesticide; When the groundwater such as well water is used to dilute the WP, such as methyl thiophanate, carbendazim, imidacloprid, and yam, it will reduce the uniformity of the liquid and reduce the suspension rate of the WP pesticide. Pharmacodynamics.
To this end, the majority of farmers friends, when diluting pesticides, it is best to use surface water such as lake water, reservoir water, river water, pond water, rice paddy water; if it is necessary to dilute pesticides with ground water, mountain spring water, etc., it should be in these waters. Adding a little rice vinegar can avoid or slow down the occurrence of the above phenomenon, and improve the effect of the chemical control pests.
PVC Film Laminated Aluminum Coil
Laminated aluminum coil is a kind of composite panel, which has a high-gloss film or colorful film covered on steel substrate. Between the film and panel is specialized adhesion.
It has plenty of appearances, metallic effect, characteristic patterns, geometrical textures. Besides, various gloss effect, high-gloss, semi-gloss and matt. Moreover, due to the specialized film, laminated aluminum coil has much property advantages like anti-corrosion, anti-dust, scratch resistance, moistureproof, easy to profile as well as uneasy to crack.
Application: Household Appliances, Interior Decoration, Building Exterior Wall Panel, etc.
