Any kind of pesticide is toxic. Therefore, when applying pesticides to crops, the safety interval must be strictly observed. Xiaobian summarizes the safety intervals of common pesticides for major crops. Let's take a look at Xiaobian. 1. Safety intervals of commonly used pesticides for food crops 1.

Safety interval of common pesticides for cotton 10% high-efficiency Baike EC 7 days; 20% amitraz EC 7 days; 10% cypermethrin EC 7 days; 50% diazinon 41 days; 73% ketone emulsion 21 days; 75% thiodicarb wettability Powder 14 days; 25% cypermethrin emulsifiable oil for 14 days; 10% Uranus emulsifiable concentrate for 14 days; 2.5% enemy killing emulsifiable oil for 14 days; 5% of Fuling emulsifiable concentrate for 14 days; 20% of chlorpyrifos for 14 days; 10% of Mapu Laike Emulsifiable oil for 14 days; 35% sulfophos emulsifiable concentrate for 14 days; 20% chlorpyrifos for 7 days; 40.7% chlorpyrifos EC for 21 days. Second, the safety interval of commonly used pesticides for vegetables 1. Safety interval of commonly used pesticides in Chinese cabbage 40% acephate emulsifiable concentrate for 7 days; 10%-. Permethrin emulsifiable concentrate for 2 days; 10% cypermethrin emulsifiable concentrate for 5 days; 2.5% of enemy killing emulsifiable concentrate for 2 days; 20% for killing butyl emulsifiable concentrate for 12 days; % quetiapine emulsifiable concentrate for 24 days; 5% of fusin emulsifiable concentrate for 3 days; 20% of chlorpyrifos for 3 days; 80% of dichlorvos emulsifiable concentrate for 5 days; 90% of crystalline trichlorfon for 7 days: 40% of dimethoate for 10 days. 2. The safety interval of commonly used pesticides in tomatoes 75% chlorothalonil wettable powder for 7 days; 10% Uranus emulsifiable concentrate for 4 days; 50% tork WP for 7 days; 10% cypermethrin emulsifiable concentrate for 1 day. 3. Safety interval of common pesticides for cucumber 40% dimethoate emulsifiable oil for 2 days; 58% metalaxyl Mn-Zn wettable powder for 1 day; 10% high-efficiency chlorhexidine emulsifiable concentrate for 3 days; 30% DI suspension for 3 days; 64% anti-bacterial WP for 3 days. Today, the introduction of the pesticide safety interval is here. To get more knowledge about pesticides , please pay attention to the Chinese pesticide network.
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Alcohol Mass Flow Meter, Alcohol Mass Flowmeter, Alcohol Coriolis Meter, Mass Flow Meter Alcohol, Coriolis Mass Meter Alcohol, ATEX, IECEx & CE approved.
Sealand meter is designed and produced according to world`s latest Coriolis technology with better appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
