CA Branch 2 Field Rep Study Guide Latest Version Rated A+ Falsifiable concentrates (EC or E) Formulations made up of the technical material, solvents and emulsifiers. Some agitation is required. Once dry, pesticide residue is barley visible. Wettable Powder (WP) These formulations are made by impregnating or coating an appropriate powder with the technical insecticide. Wettable Powders do not dissolve in water and frequent agitation is usually required. Heavy applications may leave v...

Branch 2 Pest Control Ca Questions And Answers 100% Solved dusts (d) ️️these ready to use formulations are usually made of combining an insecticide with a dust diluent ( usually inert). please not that some products, such as boric acid dusts, are almost totally comprised of boric acid and may have only small amounts of other ingredients added. many products provide an exceptional residual if kept dry. drifts are a major problem microencapsulated formulations (me) ️️microencapsu...

PeptideT or F? Peptide bonds behave as rigid planes because of partial double-bond character between the carbonyl carbon of one residue and the amide hydrogen of another residue. Correct Answer-FAlSE! B/C Hydrogen can't have a double bond, but if it stayed nitrogen it would be true. T or F? The process by which hydrophobic molecules are driven together, therefore maximizing the entropy of water, is referred to as the Hydrophobic effect. Correct Answer-TRUE! The strong electronegativity is...
