The use of pesticides is almost indispensable in the agricultural planting process. In the process of using pesticides, some people use pesticides in combination for their pursuit of effects. Of course, mixing pesticides is not impossible, but some rules need to be followed. I would like to introduce some points that need attention in the process of mixing pesticides.

Most pesticides are complex organic compounds. Even if they are acidic or alkaline pesticides, some chemical groups will react after mixing to form other unknown compounds. The use on crops is not safe and effective. Nicosulfuron, such as sulfonylureas, should not be mixed with organophosphorus pesticides.

If the pesticide of the inorganic compound is likely to be combined, the phytotoxicity may not be mixed. Such as stone sulfur mixture and Bordeaux mixture, it is not suitable for mixed use.

Commercially available pesticides are generally processed into various dosage forms, and the main components of pesticides can be mixed. If there are different dosage forms, there are also problems, such as emulsifiable products and calcium-containing wettable powders containing calcium pesticides or fillers. After mixing, the emulsification effect may be deteriorated, and even a large amount of coagulation and precipitation may occur, which seriously affects the effect of the drug.

There are also some biological agents of insecticides , such as Beauveria bassiana, Penicillium, and Acariciid, which cannot be mixed with fungicides. The insecticide of the nuclear polyhedrosis virus preparation cannot be mixed with the antiviral agent.

Therefore, the mixed use of pesticides needs to be judged according to the variety and type to determine whether they can be mixed. Reasonable mixing can sometimes lead to synergistic effects of pesticides and better results than both. For example, organophosphorus chlorpyrifos emulsifiable concentrate and pyrethroid-based beta-cypermethrin emulsifiable concentrate can exhibit synergistic effects, and the use of the two pesticides alone is much improved.

Single Axle Strain Gauge

Single axle resistance Strain Gauge is a kind of sensitive element by using resistance-strain effect to transform the strain of specimen into resistance change. It is the most widely used strain test element. The load cells used in weighing and measuring field mainly include resistance strain gauge type load cells, capacitance type load cells, vibrating string type load cells and so on, most of them are resistance strain gauge type load cells.

The resistance strain gauges produced by our company has the advantages of long liability and good uniformity, the functions of creep and temperature self compensation, suitable for batch production of alloy steel, aluminum ally and stainless steel load cells with high accuracy, and for producing other load cells and force and strain measuring elements.
