Whether it is a pesticide, a fertilizer or a plant growth regulator , whether it is a pair or a combination of the three, the following five principles must be followed:
1. Does not destroy the physical properties: after mixing, the original physical properties are maintained, and there is no phenomenon such as emulsification, suspension rate reduction, delamination, flocculation, precipitation, and crystallization of active ingredients.
2. No adverse chemical reaction occurs: no adverse chemical reactions such as acid-base neutralization, precipitation, hydrolysis, alkaline hydrolysis, acid hydrolysis, salting out or redox occur between the mixtures.
3. Does not increase toxicity and residual activity: After mixing pesticides, it is required not to increase toxicity to ensure the safety of humans and animals. Generally, moderately toxic pesticides are mixed with low- or low-residue pesticides to reduce toxicity or residue and reduce pesticide residues in fruits.
4. The method of use is as consistent as possible: the components in the mixture are relatively consistent in terms of action time, application site and object of use, and can fully exert their respective effects.
5. First try and then promote: first test in a small range, can be mixed when it proves that there is no adverse effect.
Fertilizer, pesticide, plant growth regulator mixed water
To prepare and dilute chemical fertilizers, pesticides and hormones, use clean, neutral soft water (such as river water, river water, lake water, etc.), such as hard water (water such as well water, salt water, sea water, etc. containing more calcium and magnesium ions, Hardness is 18-20 degrees), calcium and magnesium ions in water can reduce the suspension rate of wettable agents, or synthesize calcium and magnesium precipitates with emulsions in emulsifiable concentrates, destroy the emulsification performance of emulsifiable concentrates, and reduce the control effect of pesticides, and It is easy to cause phytotoxicity to crops and it is easy to block the nozzle.

Kitchen faucet is a necessary product in our kitchen. Different type can make your life more convenience.
Kitchen faucet can be made of different materials, such as copper and stainless steel. Brass kitchen faucets are mostly made of lead free brass, or DR brass or Hpb59-1. Some low end products are made of recycle brass, which would have more impurities. The stainless steel kitchen faucets are becoming more popular with the improvement of the production process.
Kitchen faucets are available in a variety of colors. Electrical chrome plated is still the most popular one though more and more colorful finished faucets are supplied in the market. The production process can be PVD, electrical plated, powder coated, ORB etc. Color options have black, matt black, white, matt white, nickel brushed, gold, rose gold, gun mental etc.
