pest
I am charged with theft of nutrients and water, and resisting chemical agents. This is a perennial that regrows from roots or fluffy seeds spread by wind. What am I?
Canada thistle
The pollutants move from level to level and get stored in organisms in the same way that food energy is stored. This effect is called
bioaccumulation.
The practice of growing only one type of plant in a specific area, often for agricultural efficiency.
Monoculture
The accumulation of salt in soil, often caused by irrigation, which can make land less fertile.
Salinization –
Insects and diseases consume over _____ percent of Canada’s annual harvest.
50 percent
I am Charged with attacking stems. It lives in the soil and attacks canola shortly after it starts to grow
Fusarium fungus
This means using a pest’s natural enemies to control it.
Biological control
The non-organic material, such as rock or sediment, from which soil develops over time.
Parent Material
When an organism, such as a pest or bacteria, develops the ability to withstand environmental pressures like pesticides or antibiotics.
Resistant –
Many of the worst weed and insect pests are organisms introduced from other countries. They are called
introduced, or exotic species.
Charged with theft of nutrients and water. This is an annual weed that sprouts any time, grows rapidly, and produces seeds before the crop is cut. Seeds will live many years in soil, then grow into very competitive weeds.
Wild oats
When a pest develops the ability to withstand chemicals or pesticides, making them ineffective.
Pesticide Resistance
The practice of using resources in a way that meets present needs without compromising future generations' ability to meet theirs.
Sustainability –
In agriculture, this refers to food grown without synthetic fertilizers or pesticides. In chemistry, it relates to compounds containing carbon.
Organic –
This is food that has been grown without the use of chemical fertilizers and chemical pesticides.
Organic food
Wanted for sucking the juice out of buds, flowers, and seeds.
Lygus bugs
method of growing plants without soil, using nutrient-rich water solutions instead.
Hydroponics
To supply water to land or crops artificially, usually through systems like sprinklers, canals, or drip irrigation.
Irrigate –
The underlying geological material, such as rock or sediment, from which soil develops over time.
Parent Material –
What makes dandelions such successful weed pests?
1. powerful roots, 2. broad leaves, 3. super seeds, 4.adaptable
Charged with infecting leaf axils and causing severe crop damage. It lives in or on the soil surface until the next crop of canola grows.
Sclerotina
A dark, organic component of soil formed from decomposed plant and animal matter, which helps retain nutrients.
Humus
The agricultural practice of growing only one type of plant in a particular area, often for efficiency but sometimes at the cost of biodiversity.
Monoculture –
non-organic material from which soil develops
