title: [Observation of molluscicidal effect of black plastic film combined with carbon amide].
abstract: OBJECTIVE
  To evaluate the molluscicidal effect of black plastic film combined with carbon amide.
  
  
  METHODS
  In Jiangdong Town, Jinhua City, the field with Oncomelania hupensis in the history was selected as experimental area and divided into 3 groups: Group One was administered with black plastic film combined with carbon amide; Group Two was administered with simple black plastic film; and Group Three was a control group.
  
  
  RESULTS
  On the 3rd, 7th, 15th, 20th and 30th day after the experiment, the mortality rates of 0. hupensis of Group One were 86.0%, 88.0%, 100%, 100% and 100% respectively, which were significantly higher than those of the control group (all P < 0.05). The differences of mortality rates between Group One and Group Two were statistically significant on the 3rd and 7th day after the experiment (Group One was superior to Group Two).
  
  
  CONCLUSIONS
  The bladk plastic film combined with carbon amide can improve the molluscicidal effect.
