As people pay more attention to food safety, they are paying more and more attention to the production requirements of agricultural products. The pesticide residue limit standard is issued by the Ministry of Health and the Ministry of Agriculture.
Latest standards for pesticide residues
At present, China has established a national standard of 197 pesticide residue limits (MRL) for 79 pesticides in 32 kinds of agricultural and sideline products, and the maximum standards for pesticide residues on fruit trees are as follows (Note: mg / kg = mg /kilogram):
1 , chlorothalonil | ≤1mg / kg | 2 , fenthion | ≤0.05mg / kg | 3 , phenbutyl tin | ≤5mg / kg |
4 , glyphosate | ≤0.1mg / kg | 5 , diflubenzuron | ≤1mg / kg | 6 , mancozeb | ≤3mg / kg (pear fruit) |
7 , mancozeb | ≤5mg / kg (small grain fruit) | 8 , DDT | ≤0.1mg / kg | 9 , trichlorfon | ≤0.1mg / kg |
10 , chlorpyrifos | ≤1mg / kg (pear fruit) | 11 , parathion | 0 | 12 , carbendazim | ≤0.5mg / kg |
13 , diazinon | ≤0.5mg / kg | 14 , fluvalerate | ≤0.5mg / kg | 15 , phorate | 0 |
16 , carbaryl | ≤2.5mg / kg | 17 , metalaxyl | ≤1mg / kg (small grain fruit) | 18 , anti-random | ≤2.5mg / kg |
19 , captan | ≤15mg / kg | 20 , Diguo | ≤1mg / kg | 21 , six six six | ≤0.2mg / kg |
22 , cyhalothrin | ≤0.2mg / kg (pear fruit) | 23 , permethrin | ≤2mg / kg | 24 , malathion | 0 |
25 , fenvalerate | ≤0.2mg / kg | 26 , alkyne | ≤5mg / kg (pear fruit) | 27 , thiazide | ≤0.5mg / kg (pear fruit) |
28 , triazolone | ≤0.2mg / kg | 29 , triazolyl tin | ≤2mg / kg (pear fruit) | 30 , chlorpyrifos | ≤0.5mg / kg |
31 , double armor | ≤0.5mg / kg (pear fruit) | 32 , tetramethylazine | ≤1 mg | 33 , phoxim | ≤0.05mg / kg |
34 , bromo oxime ester | ≤5mg / kg ( pruned fruit) | 35 , deltamethrin | ≤0.1mg / kg (skin edible) | 36 , imipenem | ≤0.5mg / kg |
37 , acephate | ≤0.5mg / kg | 38 , isourea | ≤10mg / kg (pear fruit) | 39 , dichlorvos | ≤0.2mg / kg |
It is hoped that the implementation of the pesticide residue limit standard will make people's table more healthy and greener.
Peristaltic Feeding Pump Characteristic
1. Clean and pollution-free: the fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
