    10 Common Mistakes at Plant Protection Spraying

         In recent years, pesticides have become an essential production material in agriculture. Since the lack knowledge of pesticide application technology is very common, farmers are likely to use pesticides incorrectly. Here are 10 tips at pesticides application.


    1. Inaccurate handling timing

         It’s helpful to know when to control pests or weeds from impeding crops or plants growing. Inaccurate handling time like spraying pesticides after rice already appeared symptoms of dead stems, white or even dead ears means late control of stem borers and much less effectiveness. Hence it’s
    important to detect pests or weeds as earlier as you can, and handle them at the right time.  


    2. Improper spraying position

         All pests have their habitual positions when feeding on crops. Spraying at improper positions not only wastes pesticides but also causes ineffectiveness. Please refer to professional guide according to different pest objectives for better result.


    3. Increasing pesticides or herbicides resistance
         Now more and more chemicals are applied to control diseases, pests and weeds. On the other side, diseases, pests and weeds are also
    strengthening their abilities to fight against chemicals, pesticides and herbicides respectively. These abilities seem multiplied at recent years. It becomes harder for chemist to find better solutions to restrain the fight back.

    4. Wrong controlling objective
         As a lack of knowledge, farmers are likely to incorrectly distinguish controlling objectives since the similar symptoms of unhealthy plants caused by plant disease, pest-caused illness and weed inhibition of plant growing. For example, cotton red leaf blight has symptoms that leaf vain turn green, mesophyll turns purple red like pork liver, leaf blades warped downward and finally dried up and fell off. It’s quite like red spider jeopardizing on cottons. Parasitic cuscuta chinensis has the same appearance with ill soybean caused by meloidogyne. Hence the wrong controlling objective and bad result happens.

    5. Pesticides wasted while spraying

           So far, sprayers are still traditional manual operated backpack type for decades. Experiment shows that the traditional sprayer works with poor pesticides adhesiveness and low deposition rate on plants and endangers operator’s healthiness. Pesticides are mostly wasted on soils and into waters, and polluted our environment. To effectively control pesticide waste, low-volume sprayer, ultra-low volume sprayer, mist sprayer, and electrostatic spray should be widely promoted.

          The plant protection drone adopts advanced ultra-low volume spray technology that saves an average of 50% volume of pesticides, and reduces lots of pesticide residues. The downward airflow generated by the drone helps pesticides penetrate plants from top to bottom and sprays evenly on every parts of the plants.

    6. Pesticide Limitations

          Pesticides have their own limitations. A pesticide is effective to certain diseases, pests and weeds, and meanwhile ineffective to others or even have side effects. For example, triazophos controls stem borers, cotton bollworm and other lepidopteran well, and has obvious ovicidal effects. However, it stimulates plant hoppers to spawn and become rampant again.

    7. Inappropriate spraying timing

          Diseases, pests, and weeds have their own break-out circumstance and unique biological clocks. For example, pieris rapae, cotton leaf roller moths, and rice stem borers are active during the day when there is sufficient sunlight. Lepidoptera and some codling moth pests are active, mate and spawn at night. Therefore, spraying right pesticides at appropriate time according to different pests’ biological clocks makes better control effect.

    8. Ignores weather conditions

         The control effect of pesticides is related to different weather conditions. Temperatures, humidity, light, wind all have an impact on the occurrences
    and activities of pests, and affect controlling effectiveness. Herbicides will not work when sprayed at below 8 °C; Pesticides easily evaporate when sprayed at strong sunshine above 35 °C ; Pesticides drift away at heavy wind conditions; make sure there will be no rain within next 24 hours when spraying EC pesticides, and as for contact pesticides, there must be no rain within next 48 hours.

    9. Less natural enemies

          Pests’ natural enemies have also been killed while using highly toxic and high-residue pesticides to control pests in the past years. Pests become more rampant when ecological balance is destroyed. A vicious ecological circle forms and impacts on agriculture.

    10. Inappropriate water qualities

          People are likely to choose inappropriate waters while mixing pesticides since the common unawareness of water quality differences. Waters, like in well, at mining area, or springs at mountain areas contains minerals are called hard waters. Hard waters decompose active ingredients of pesticides. Hence soft waters in streams, rivers, and ponds are better choice for mixing pesticides. Turbid waters are also bad choices that affect pesticide effectiveness.
