Treating diseases and preventing insects is an important part of doing a good job in agricultural production and increasing food production. Remind farmers friends: 7 taboos for the preparation of pesticides .
First, use well water to dispense medicine
The well water contains more minerals such as calcium and magnesium, and they are easy to react with the chemical solution to form a precipitate, thereby reducing the efficacy.
Second, sewage dispensing
The sewage contains many impurities, and the dispensing will block the nozzle, which will also destroy the stability of the liquid and reduce the efficacy.
Third, the application of rain and rain and high temperature
Spraying the wind will make the pesticides drift; when applied in rainy days, the liquid is washed away by rain to reduce the efficacy; when applied at high temperature, it is prone to phytotoxicity and poisoning. Therefore, the best time to apply is: 8 am, 11 am, 4 pm - 6 pm. The weather is fine and the breeze is applied.
Fourth, the abuse of pesticides
The corresponding pesticides should be used according to the crop type, the control object and the performance of the drug, so as to achieve the right medicine, and avoid blindly increasing the application amount, resulting in enhanced pest resistance, reducing the control effect, and easily causing phytotoxicity.
Five, flowering spray
Crops and fruit trees are applied at the flowering stage and are prone to phytotoxicity.
6. Pre-harvest application
Since pesticides can cause residues on crops, residues can cause food poisoning if applied before harvesting.
Seven, one medicine used
Long-term use of one or a dosage form of pesticides is most likely to cause pest resistance and reduce the control effect, so it should be used alternately.

Our UHMWPE Marine Fenders are made from virgin uhmwpe material, which is much superior to wood and rubber in building marine constructions or coastal protective structures. UHMWPE marine fenders allow vessels to glide easily along the surface, protecting hulls and dock structures. Impervious to marine bore worms with minumum cleaning.
Application
1.Harbour building: the outline of the dock wall, used to cover the friction blocks of wood and rubber
2. Truck Dock: Fenders/Blocks for Dock Protection
3. Ship: low friction bushing, friction / wear strip
4. Floating dock: Wear pads at the dock where the predator encounters, support pivots, fenders, slides
