Xinjiang Moyu area when the cotton seedlings unearthed to one or two true leaves, it is a large number of yellow tiger eggs hatch, juvenile larvae of harmful period; application of drug dressing, poisoning with poison, is an important method of prevention and control one. Since the implementation of 666 seed dressing prevention and control in 1959, in order to seek efficient pesticides that have no inhibitory effect on the growth of cotton seedlings, a good 25% of seven-chlorine seed dressing was tried on this site and some communes from 1965 to 1967 Effect. Field demonstration in 1972 to verify the effectiveness of prevention and treatment. First, the 25% seven ammonia emulsion seedling prevention and control of cotton seedlings of yellow tiger and field comparison (a) test materials and projects 1. Materials 1965 test for the active ingredient containing 25% of seven chlorine emulsion, the Shanghai Institute of Pesticide Provided; 1966 tested with 25% of the active ingredient heptachlor emulsion prepared by the Xinjiang Academy of Agricultural Sciences plant protection (heptachlor crude oil supplied by Shanghai Electric plant).
