Crop Protection Flashcards
Weed that completes its life cycle within one year.
Annual
Biological control
Reduction of a pest population by the deliberate introduction of one of its pests, predators or pathogens.
Means of control of weeds, pests and pathogens using herbicides, pesticides and fungicides.
Chemical
Contact herbicide
Type of non-selective herbicide that destroys all green plant tissues which it meets.
Agricultural practice whereby each of a series of different crop plants is grown in turn on the same piece of ground.
Crop rotation
Cultural
Traditional non chemical means of controlling weeds, pests and pathogens that affect crop plants.
Combination of techniques including chemical, biological and cultural means of control.
Integrated pest management
Monoculture
Vast population of a single species cultivated for economic efficiency.
Pathogen
Disease-causing micro-organism
Weed that continues to grow for several years.
Perennial
Non-biodegradable chemical whose molecules accumulate along a food chain.
Persistent
Pesticide
Chemical used to control pests.
Resistant
Type of pest that survives treatment by a pesticide and enjoys a selective advantage.
Systemic herbicide
