Can sugarcane herbicides and insecticides be mixed and used together?
First: The weed-control spectrum of the two herbicides should differ. Second: A fast-acting agent should be mixed with a slow-acting agent, and a long-lasting agent should be mixed with a short-lasting agent. Third: An agent with high diffusibility and mobility in the soil should be mixed with an agent with low diffusibility and mobility. Fourth: ...

Third: An agent with high diffusibility and mobility in the soil should be mixed with an agent with low diffusibility and mobility.
Fourth: After two or more agents are mixed, they should produce a synergistic or additive effect, and at the very least must not antagonize each other or cause phytotoxicity to crops.
Fifth: The application period and method of the two agents must match.
