1. Pay attention to the type of pesticide and the time of application. Different types of herbicides have different application times. Herbicides that cause the weeds to die through the foliage or contact of the plant foliage are best sprayed when large areas of young weeds are formed but have not yet ageed. If paraquat is used, it should be sprayed when the weeds are in 3-4 leaves.
2, pay attention to medication methods a lot of inactivated herbicides will occur once the contact with the fruit tree leaves phytotoxicity, spraying should make the nozzle down, directed spray, to avoid spraying on fruit trees or intercropping.
3, strictly control the amount of medication as far as possible to effectively eliminate weeds without causing waste. If 41% Dalinon is used, it is generally 180-250 ml per mu and 40-50 kg water. To increase efficacy, add 0.2% detergent.
4. Pay attention to the water quality. The water used for the preparation must be clean and free of pollution. Do not use muddy water or muddy water. Do not mix with alkaline pesticides and chemical fertilizers.
5, pay attention to the safe use of drugs Most agents harm the human body, should try to avoid touching the skin and eyes, once contact may cause irritation. If you have symptoms of allergy, rinse immediately with clean water and seek medical advice.
6, pay attention to the cleaning and storage of equipment Sprayer should be cleaned, or easy to cause parts corrosion. The sprayer is best used for special purposes. It should not be used to spray other pesticides and foliar fertilizers as much as possible to avoid phytotoxicity.
7. Note that alternate spraying of the same agent for several consecutive sprayings will reduce the weeding effect. An agent should not be used continuously for more than three years.
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system.
It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
