Document Summary
6. 1 modern crop production practices: young infants who consume well water contaminated with nitrates may be made ill as nitrates converted to nitrites can change the haemoglobin structure which prevents it from carrying o2. This condition is known as methemoglobinemia/blue baby syndrome: a pest is any animal or plant that interferes with human wellbeing or interests by carrying disease or causing discomfort in people. Does not refer to a pathogen but rather a vector such as an insect or rodent: an active ingredient is a chemical that is intended to kill a pest, types of pesticides: Fungicides are used to control fungal growth in the environment: critical to the protection of fruits grown in wet conditions, commonly used in cranberry bogs and apple orchards. Pest can develop resistance to the pesticide which creates pressure to develop new pesticides. Target pests are the pest that consume the crop which farmers wish to get rid of.
