Advanced Crop Production: Weed Biology and Management

These flashcards cover key vocabulary and concepts related to crop protection, weed biology, and management strategies as discussed in the lecture.

Crop Protection

Practices, tools, and technologies used to safeguard crops against biotic threats to minimize yield and quality losses.

Weed

A plant whose virtues have not yet been discovered; any plant other than the crop sown.

Herbicide Resistance

The ability of a weed species to survive applications of herbicides that once killed them.

Selective Herbicides

Herbicides that are inhibitory to weeds but not the crop; they control some but not all weed species.

Non-selective Herbicides

Herbicides that inhibit all or most plants, including crops and weeds.

Weed Ecology

The study of ecological roles and interactions of weeds within agroecosystems.

Vavilovian Mimicry

Morphological, phenological, and physiological mimicry of crops by weeds.

Seed Dormancy

A trait that allows seeds to remain viable in the soil for extended periods without germinating.

Herbicide Mode of Action

The specific biochemical mechanism through which a herbicide acts on a plant.

Adaptive Traits

Characteristics of weeds that enhance their survival and competitive ability in agroecosystems.
