41
Q

LC50

A

The concentration of a pesticide, usually in air or water, that can kill 50 percent of a test population of animals when ingested or absorbed through the skin. LC 50 is usually expressed in parts per million (ppm). The lower the LC 50 value, the more acutely toxic the chemical.

42
Q

LD50

A

The dose or amount of pesticide that can kill 50 percent of the test animals when ingested or absorbed through the skin. LD 50 is expressed in milligrams of chemical per kilogram of body weight of the test animal (mg/kg). The lower the LD 50 the more acutely toxic the chemical.

43
Q

A

A state level plan to provide assistance and coordination to responsible agencies, organizations, growers and beekeepers for the protection of insect pollinators.

44
Q
