write an essay about weed classification according to habitat

Answer 1

General classification of weeds

Most farmers use a different method of classifying weeds since it is easier to understand and separate each weed from another in order to control them.

Classification according to growth season length

Annuals: These weeds complete their life-cycle in one year. Due to the abundance of dormant seed and fast growth of annuals, they are very persistent and cost more to control than most other weeds. The most common type of weeds are annuals. There are two types of annuals (1) summer annuals and (2) winter annuals.

Summer annuals: Most of these weeds germinate in spring, mature during summer and die in the fall. Summer weeds include cockleburs, morning glories, pigweeds, crab grasses etc.

Winter annuals: These weeds germinate in the fall and winter and mature in the spring or early summer before the plants die. Common winter annuals are chickweed, cornflower, corn cockle, hairy chess etc.

Biennials: These weeds have a vegetative growth cycle in the first year and a reproductive growth cycle in the second year. Common biennials are wild carrot, bull thistle and burdock.

Perennial: Depending on the climatic conditions they will grow either vegetatively or reproductively. They may grow for longer than two years. Perennials are grouped into simple perennials and creeping perennials. Simple perennials reproduce through seed. Creeping perennials reproduce by creeping root systems and may reproduce through seed. Once a field is infested with a creeping perennial, it is the most difficult to eradicate. It usually takes at least 2 years to rid a field of creeping perennials.

Classification according to habitat

Pioneer weeds: They are only found on soils which have been disturbed and where other plants will not grow due to the harsh environmental conditions.

Facultative or optional weeds: These are weeds that are found in nature and between commercial crops where the soil is disturbed.
