Look at your second dense white spot, which is the nymph-faded shell of the whitefly (also known as white lice). It is recommended to fight against whitefly, iprodione, or procymidone. Whitefly has different resistance to pesticides. It is usually 20% nitenpyram or 50% thiamethoxam or 50% dinotefuran or 50% pymetrozine or 20% thiacloprid, etc. Mixing 10% bifenthrin is also acceptable; killing eggs plus 20 % buprofezin, but this ingredient is not effective for adults, it must be used in conjunction with other pesticides, 20% buprofezin can not be used for radish, leafy vegetables, phytotoxicity. 30% pyriproxyfen is also effective in killing eggs. It is not effective for adults and is better used with the above products. Select the above ingredients, suggest adding silicone spray agent, fight drugs sooner or later, hit it through.
