Can Bordeaux liquid kill insects and fungicides?

Bordeaux liquid is an inorganic copper fungicide, which has been used in pesticide cultivation in China for many years, but there are many misunderstandings in its use. Some farmers believe that Bordeaux liquid is an alkaline pesticide and should not be mixed with imidacloprid, acetamiprid, ethyl phosphorus aluminum and so on.

The first thing to say is that Bordeaux liquid is a weakly alkaline mixture of copper sulfate and quicklime, which does not immediately react strongly with acidic agents, let alone neutralize the efficacy of insecticides and fungicides immediately. Insecticides can be added with imidacloprid, acetamiprid, thiamethoxazine, perchlorate, methylvitamin high chlorine, etc.; to kill red spiders, you can add acarbazol, metoproyanide, etc.; foliar fertilizer can be added; naphthylacetic acid can be added to prevent pre-harvest fruit drop.

It should be solemnly reminded that the amount of insecticidal and germicidal drugs added should be increased by about 30% (for example, 1000 times at ordinary times, 700 times when added to Bordeaux liquid). It must be used now, and it must not be kept for too long.
