46. What is an inorganic pesticide? Synthetic, usually toxic, lacks carbon
47. What is a microbial pesticide? Bacteria, fungi, viruses, or other organisms causing pest diseases
48. What is selectivity in pesticides? Range of pests affected; broad or narrow spectrum
49. What is persistence in pesticides? Duration of residual activity (weeks, months, years)
50. How are pesticides named? Trade name, common name, chemical name
51. What are inorganic insecticides used for? Target stressed or young insects
52. What are IGRs? Insect Growth Regulators; disrupt insect development

66. What does D stand for? Dust
67. What does G stand for? Granules
68. What does P or PS stand for? Pellets
69. What do penetrants do? Aid in pesticide absorption into plants

70. What is the most important federal pesticide law? FIFRA (Federal Insecticide, Fungicide, Rodenticide Act)
71. What is involved in pesticide registration? Prove safety, benefits outweigh risks, correct labeling
72. Why are some products classified as restricted use? Risks outweigh benefits unless used by trained professionals
73. When state laws are stricter than federal laws, which take precedence? The stricter law
74. Criteria for a private applicator? Use pesticides on land owned or rented by the farmer; applications for pay limited to 500 acres
