The previously updated article “What can mineral potassium humate be used with? (Part 1)” answered the question of whether mineral potassium humate can be used with chemical fertilizers and trace element fertilizers. This article continues to answer the question of whether mineral potassium humate can be used with pesticides, fungicides, plant growth regulators, and microbial agents.
3. Can mineral potassium humate be used with pesticides?
Mineral potassium humate can improve the effect of pesticides and reduce pesticide residues in fruit and vegetable products. However, it is necessary to pay attention when mixing and using. If the organic solvent is acidic, then use it with caution. It is insoluble in acid and alkali, which can easily make the pesticide ineffective. If the organic solvent contains high-valent metal ions, use it with caution as well, which can easily cause flocculation and make the pesticide ineffective.
Suggestion: Perform a compounding experiment before mixing and using. If there is flocculation and stratification on the appearance, it is recommended to use them separately.
4. Can mineral potassium humate be mixed with fungicides?
Mineral potassium humate contains many functional groups, and combining with fungicides can better improve the fungicidal effect. When using it, you should also pay attention to the acidity and alkalinity of the fungicide, and the content of metal ions. If you are not sure about the above information, it is best to do a compounding experiment before application. If it is still a stable solution after 12 hours, it is recommended to mix it.
5. Can mineral potassium humate be mixed with plant growth regulators (hormones, such as brassinolide, chlormequat, paclobutrazol)?
Most plant growth regulators will cause adverse effects on crops in the later stage after use, such as wrinkled and deformed seedlings, wrinkled leaves and even growing points or fern leaf virus symptoms on leaves, malnutrition and deformity of fruits, etc. When used simultaneously with mineral potassium humate, it can not only balance and regulate plant growth, but also alleviate adverse effects in the later stage. It is recommended to do a compounding experiment when using it.
