Technical material can be used to make a substance or mixture in medicine, and it becomes an active ingredient in medicine when making medicine. When it comes pesticide, popular saying is not processed pesticide. Technical materials are also divided into various forms, such as solid technical materials are called raw powder, and liquid technical materials are called crude oil. Just as pesticide formulations can be divided into solid and liquid, there are also wettable powder, granules and so on.
Parent drug refers to the mixture obtained by dissolving active ingredients with high content and solvent. Generally speaking, it can be said that the pesticide is formulated from the original drug, but it is different from the processed pesticide preparation.
Technical material and parent drug can be used as raw materials for processing preparations, but they are not suitable for direct use in crop fields. We usually use pesticide preparations which have been processed.
Since the concentration of the technical material is high and has not been processed, is it better and more efficient?
The answer is the efficiency of direct use of technical materials is low, the pollution is large, and there may be safety problems and pesticide harm.
Most of the technical materials are not directly soluble in water, so they need to be made into preparations. The pesticides and herbicides we usually buy are all pesticide preparations after processing.
Most of the preparations are based on the technical material, and then add other ingredients, such as surfactants, technical material, solvents, etc. Finally, they are prepared to be suitable for agricultural use.
If it is not made into preparation, the utilization rate of pesticide is low, and the dispersion performance is not very good, which is more likely to cause environmental pollution and safety problems.
And the technical material belongs to high toxicity, and it becomes a low toxicity pesticide after it is made into preparation, which reduces the harm to human body.
When we use pesticides, the main purpose is to control diseases, pests and weeds. In order to achieve this goal, it will not harm the crops, so we need to pay attention to:
① To use it according to the dosage of pesticide instructions, do not easily increase the dose.
② Do not spray again to avoid pesticide damage.
③ It is better to use pesticide in windless weather to reduce the probability of pesticide drift.
