As we all know, thrips damage crop parts such as the leaves, flowers and fruits of vegetables. However, their activities are very subtle, spray control is difficult to get a good control effect. Is there any other effective measure to control this kind of subtle pests in organic agriculture (chemical pesticides are forbidden)? Thanks for your help.

Foliar application of neem seed kernel extract or biodynamic liquid pesticides prepared with herbal plant extract will mange the thrips and other insect in organic farming. This spray at intial stage is more effective than at serious stsge.
