I just bought mint at the flower, bird, fish and insect market. I wonder if there are any pesticides. I want to cook.

The mint bought in the flower, bird, fish and insect market is mainly for ornamental purposes, and it is difficult to ensure that the flower seedlings grow strong without pesticides. For the sake of health, it is best not to cook. Because there is no pesticide residue detection department in the flower, bird, fish and insect market! If you want to eat mint, you'd better go to a big farmer's market or supermarket to buy it.

The main pests and diseases of mint are leaf blight, rust and armyworm. Spot blight should be removed in time, buried in the mountains or burned to reduce the source of infection, and 120 times bordeaux solution or 500 times 65% zineb solution should be sprayed. Should 15% triadimefon wettable powder be used in the early stage of rust? 1000 times solution or 40% carbendazim gel suspension 800 times solution spray. Spraying 90% trichlorfon 1000 times solution or 2.5% deltamethrin, or 20% deltamethrin 1500 times solution on moths?
