Physical and Biological Responses for Several Suspension Formulations

Source

The deposition of suspension particles was studied using scanning electron microscope, neutron activation analysis, and gas chromatograph-fluorometer methods. The quantity of suspension particles deposited was always less than should have been deposited when evaporation did not confound the results. The importance of several materials used as gustatory adjuvants for Heliothis zea larvae is identified. In general, inclusion of a flour in a virus-gustatory adjuvant suspension increased insect mortalities more than other materials evaluated. Mortality increased almost linearly with the flour concentration (up to about 10 percent) for a given virus dosage. The virus half-life was greater for a cottonseed flour adjuvant (Coax) than for a soybean adjuvant, and both adjuvants resulted in longer half-lives than a virus-water suspension.
