There are often people who ask you if this pesticide is mixed with the pesticide. For example, someone will ask you if you want to mix it with carbendazim? You can kill it with a nail. Some pesticide products are also often noted in the matter of concern: the pesticide cannot be mixed with strong alkaline pesticides. So which pesticides are strongly alkaline?
In fact, most pesticides are generally weakly acidic, and only a few pesticides are strongly alkaline. Because the strong base and the acid should undergo a neutralization reaction, the mixed effect will affect the drug effect, and it is likely to cause phytotoxicity. In addition, other pesticides can basically be mixed with each other. However, when mixing pesticides, pay attention to the concentration of the whole liquid. For example, when some retailers dispense medicine, in a backpack water, this medicine adds 10 grams, and the medicine adds 20 grams. A total of five or six medicines are added. The total concentration is very high, and the backpack can easily cause phytotoxicity when used to spray crops, especially at high temperatures, in greenhouses, or when crops are blooming or young.
Acetochlor
Acetochlor can never be used on watermelon, strawberry, and lettuce. If used, watermelon must be dead, and strawberries must be dead. Every year, acetochlor is afflicted with watermelon and strawberry. There is also acetochlor which should not be recommended on many crops unless acetochlor is registered on this crop. It is also important to note that even if acetochlor is used on crops that have already been registered, water cannot be accumulated during use, otherwise it is easily phytotoxic.
2, chlorpyrifos
Can not be used in the seedling stage of melons and lettuce, if used, it is also 100% phytotoxic. Even if other vegetables are used, try not to use chlorpyrifos, otherwise it is easy to burn leaves.
3. Inorganic copper preparation
For example, copper hydroxide, copper sulfate, do not mix other pesticides , especially foliar fertilizers, otherwise it will easily cause falling flowers and fruit.
4, triazole fungicide
That is, there is a "azole" word fungicide, such as triazolone, tebuconazole, flusilazole, propiconazole, etc., the concentration should be controlled when used, can not be used excessively, otherwise it can easily inhibit crop growth and easily produce phytotoxicity. However, the difenoconazole in the triazole fungicide is safer and has little to do with excess use.
5, alkyne
It is easy to cause phytotoxicity when used on vegetables.
