11 items that must be paid attention to when preparing pesticides , high-efficiency application, pay attention to the details of pesticide application, improve efficiency and reduce harm.
First, the dispensing personnel should understand and master the nature and formulation technology of the pesticide, and prepare it in strict accordance with the methods and procedures specified in the label or the instructions.
Second, during the preparation of pesticides, it is necessary to pay attention to safety, wear protective gloves such as gloves and masks, and guard against human damage.
Third, the medicine should choose a safe place away from drinking water sources and settlements.
Fourth, avoid using sewage to prepare pesticides. Because there are many impurities in the sewage, it is easy to block the spray nozzle by using the medicine, and it will also destroy the suspension of the liquid to cause precipitation. Remember not to use well water to dispense. 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.
Fifth, don't spend time spraying. Crops and fruit trees are applied at the flowering stage and are prone to phytotoxicity.
Sixth, avoid increasing the amount of water arbitrarily. Because too much water will reduce the concentration of pesticides, so that the efficacy is reduced or even completely ineffective. In addition, excessive water addition can also cause pesticide loss and environmental pollution.
Seventh, when mixing several pesticides, be cautious, especially for some pesticides with strong acid and alkali, and those that cannot be mixed must not be mixed.
Eighth, do not apply before the application. Since pesticides can cause residues on crops, residues can cause food poisoning if applied before harvesting.
Ninth, don't use one medicine. 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.
Tenth, do not abuse 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.
Eleventh, do not apply in rainy days and high temperatures. 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 application time is: 8:00 am, 11:00 am, 4 pm, 6 pm. The weather is fine and the breeze is applied.
More pesticide knowledge , please pay attention to China Pesticide Network
Mining operators are constrained by the unique challenges of mining underground which typically create significant line-of-site and environmental barriers to effective communications. The customer was especially impressed by the RF modelling which was provided as part of the scoping. The modelling significantly reduced project risk by providing a signal strength heatmap with estimations of data throughput in each part of the tunnel system.
Real-time video monitoring
Better access to operations data to support mine performance planning, create a foundation to implement more reliable Mine Communications.
