Dichlorprop-P and bentazone have been widely used in the prevention and control of weeds in wheat field ecosystems. There is a concern that pesticide residues and metabolites remain on or in the wheat. Thus, the study of the determination and monitoring of their residues in wheat has important significance.

Article Synopsis
- LH-2010A is a newly developed fungicide effective against cucurbit downy mildew, with studies conducted in China assessing its dissipation and residue levels in cucumbers.
- Average recoveries of LH-2010A in cucumber reached 94.0-106.2%, while soil recoveries were 84.4-98.7%, indicating reliable detection methods.
- The fungicide had half-lives of 2.8-4.2 days in cucumber and 6.3-9.4 days in soil, with recommended maximum residue limits (MRL) established at 0.5 mg/kg for safety in greenhouse ecosystems.
