Final answer:
In general, refilling herbicide containers with different types of herbicides is not allowed without explicit guidance and approval, due to the risk of contamination and chemical reactions.
Step-by-step explanation:
The question pertains to whether you can refill an empty new soybean pre-emergence grass herbicide container with a different type, namely a soybean post-emergence herbicide. Generally, the practice of refilling herbicide containers requires adherence to specific regulations to prevent contamination and ensure the safe use of the chemicals. Without explicit guidance and approval regarding such practices, the assumption should be that refilling containers with different herbicides (such as atrazine and glyphosate) is not permissible. These herbicides have different purposes and chemical compositions, and mixing or storing them improperly could lead to reduced effectiveness or harmful chemical reactions.
