T/F - True Soil and plant surfaces may contain pesticide residue even when they are not directly sprayed with pesticide.T/F - True EPA sets two kinds of tolerances--------tolerances for pesticides that indirectly contact food; and tolerances for pesticides applied directly to food. - Negligible residue, finite "Preslaughter interval" or "preharvest interval" refers to the number of days allowed between the last pesticide application and the slaughter or harvest day. - Least T/F No pesticide may be bought, sold or used in the United States until it has federal registration for the product, the use and the label. - True Sometimes even small environmental changes can greatly reduce the chances of survival for fish and wildlife.
