Abstract: The residues of chlorothalonil, carbendazim, mancozeb and imidacloprid in cucumber from South China and North China cultivars were analyzed at 2-day intervals 1 day after administration under various conditions. The results showed that pesticide residues decreased with prolonged time interval between administration and harvesting. Pesticide residues in South China cultivar was significantly lower than those in North China cultivar. When cucumber was protected against diseases by leaf spray, pesticide residues in cucumber fruits did not generally exceed the national maximum limits.

Key words: greenhouse, cucumber, South China cultivar, North China cultivar, pesticide residue, chlorothalonil, carbendazim, mancozeb, imidacloprid
