Fundamentals
This waxy layer on a leaf is a major barrier to herbicide absorption
What is a cuticle?
Glyphosate is the _________ name for RoundUp herbicide.
What is common name?
This is the inherent ability of a species to survive and reproduce after herbicide treatment.
What is herbicide tolerance?
These herbicides need to be applied before the weed emerges.
What are preemergence herbicides?
RoundUp Ready GMO crops can tolerate this herbicide.
What is glyphosate?
These substances which catalyze reactions are often herbicide targets
What are enzymes?
This is a common trade name for glyphosate herbicide.
What is Roundup?
Using the same herbicide repeatedly can select for herbicide resistant __________
What are biotype?
This process describes herbicide binding to the soil colloid and organic matter.
What is adsorption?
Non-GMO Soybeans and tomatoes are very sensitive to this herbicide which certain GMO soybeans can tolerate.
What is dicamba?
Surfactants typically reduce this physical property of water.
What is surface tension?
5-enolpyruvoyl-shikimate-3-phosphate synthase (EPSPS) is the __________ for glyphosate
What is target site?
This resistance mechanism is an over production of the target site enzyme.
What is gene amplification?
These organisms are primarily responsible for herbicide degradation in the soil.
What are microbes or bacteria?
This describes the pressure exerted by a vapor in equilibrium with a liquid or solid form.
What is vapor pressure?
Herbicide translocation is typically low during this phase of plant growth.
What is the reproductive phase?
N-(Phosphonomethyl)glycine is the ________ name for RoundUp herbicides
What is the chemical name?
This term describes a weed biotype with resistance to two or more herbicides with different modes of action.
What is multiple resistance?
This function is used to describe and compare adsorbance of different herbicides to the soil.
This localized weather phenomenon creates conditions conducive to off-target injury if an herbicide like dicamba is applied near sensitive plants.
What is a temperature inversion?
This biochemical process often results in selectivity of the herbicide to kill the weed and not injure the crop
What is metabolism?
This legal document provides important information regarding the active ingredient and use rates for every herbicide product available.
What is the product label?
Integrated weed management can prevent herbicide resistance by reducing this type of pressure on the weed population.
What is selection?
The half-life of an herbicide typically _______ as soil temperature increases.
Decreases
This agency determines whether dicamba can legally be applied to crops engineered with dicamba tolerance.
What is the EPA?
