Abstract Chinese cabbage(Brassica chinensis Linn.)was sprayed or irrigated with various doses of single light rare earth nitrate or their different compounds;pesticide residue was tested 3 days after spraying decamethrin.The result showed that decamethrin s degradation was suppressed by high concentrations of rare earth nitrate solutions(≥1.8×10~ -5 mg·L~ -1 ),and promoted by low concentrations(≤1.8×10~ -6 mg·L~ -1 ).Additionally,the suppression or promotion of pesticide s degradation was influenced by the treating ...
