Tips for Boosting Herbicide Effectiveness
Now the pesticides used in drones are all common pesticides used in plant protection machinery. Due to the weak power of the plant protection aircraft, the drug load is generally only 10-20 kg. If it is used as usual, the pesticides are diluted with a lot of water and sprayed.
The poor efficacy of wholesale herbicides is mostly caused by the lack of uniform mixing. First, let’s explain the secondary dilution, which means to add a small amount of water to make a mother liquor, and then pour it into a sprayer with a certain amount of water, then add the amount of water to be added, and stir while adding, mix thoroughly and dilute to the required concentration.
In this way, the wholesale herbicide liquid can be dispersed more evenly in the medicine equipment. It is like making milk powder. It is difficult to evenly pour the water into the milk bottle at one time. Dilute it with a small amount of water once and then add the right amount of water, the effect will be much better. So, don't save this step, to be even, you must do it!
Additives
In the use of herbicides, adding some adjuvants in an appropriate amount can reduce the surface tension of the spray liquid, increase the wetting and spreading of the liquid, increase the retention of the herbicide on the leaf surface, delay the drying time of the liquid, and improve the penetration and expansion of the drug. absorb. Some vegetable oils, mineral oils, etc. are all adjuvants, but pay attention to the amount. Adjuvants increase the efficacy of herbicides and also increase the phytotoxicity, so don't be too much.
Try to use two herbicides
This can double insurance, the truth and we have a treatment method called cocktail therapy is the same. The two herbicides can greatly improve the herbicidal spectrum and effect. For example, using pendimethalin + trifluralin or promethazine or promethazine can achieve very good results.
