a large tractor-mounted sprayer used for broad area applications.
a method of applying herbicide through soil injection techniques.
a type of herbicide that is applied in liquid form over large fields.
hand held or backpack sprayer that delivers a pre-measured dose of concentrated
herbicide to the base of target vegetation.
Term 3 of 68

__________ and ___________.
June and July
March and April
April and May
August and September
Term 5 of 68
Four stages of weed development and briefly describe each.
Dormancy, revival, reproduction, and extinction
Germination, flowering, wilting, and decay
Sprouting, growth, harvest, and storage
Seedling, vegetative, seed production, maturity
Term 6 of 68
what are the advantages and disadvantages of granular and pellet applications?
good for small areas
broadcast applications can cause damage to non-target vegetation.
applying too much chemical to the cut surface, making improper frilling or girdling cuts.
low volume ground, high volume ground, aerial application.
results from regulator you choose, rates must be determined, results will vary with timing of
application, stage of growth of given species will affect results, impacts on environmental
conditions.
, Term 7 of 68
________ plants live on and get their food from host.
Parasitic seed plants
Deciduous plants
Photosynthetic plants
Perennial plants
Term 8 of 68
How can plant leaf shape affect herbicidal action?
broad leaves hold herbicide longer, herbicide will run or bounce off narrow, upright leaves.
broad leaves increase photosynthesis, which reduces the need for herbicides.
leaf shape has no impact on herbicide effectiveness, only the type of herbicide matters.
narrow leaves absorb herbicide more effectively, leading to quicker plant death.
Term 9 of 68
when are the best results from soil residual herbicides achieved?
late summer when weeds are fully grown.
early spring before the weeds emerge or when they are small.
anytime during the year regardless of weed size.
only during winter months when the ground is frozen.
