Crop Protection Flashcards
Annual
Weed that completes its life cycle within one year.
Biological Control
Reduction of a pest population by the deliberate introduction of one of its natural enemies.
Chemical
Means of control of weeds, pests and pathogens using herbicides, pesticides and fungicides.
Contact
Type of non-selective herbicide that destroys all green plant tissue which it meets.
Crop Rotation
Agricultural practice whereby each of a series of different crop plants is grown in turn on the same piece of ground.
Cultural
Traditional non-chemical means of controlling weeds, pests and pathogens that affect crop plants.
Integrated Pest Management
Combination of techniques including chemical, biological and cultural means of control.
Monoculture
Vast population of a single species cultivated for economic efficiency.
Pathogen
Disease-causing micro-organism.
Perennial
Weed that continues to grow for several years.
Persistent
Non-biodegradable chemical whose molecules accumulate along a food chain.
Pesticide
Chemical used to control pests.
Resistant
Type of pest that survives treatment by a pesticide and enjoys a selective advantage.
Selective
Type of herbicide that mimics plant growth substances and kills broad-leaved plants by stimulating their growth to a harmful extent.
Systemic
Type of herbicide that is absorbed by a plant and transported internally to all parts where it has a lethal effect.
Weed
Unwanted plant that poses economic problems when it is able to multiply among and compete with a crop.
Weed that completes its life cycle within one year.
