Illinois Field Crops Applicator
All soil implemented herbicides need to move into the soil, which may be done by using -
ANS-mechanical techniques or rain
most weed seeds germinate within the top 2 inch of soil
An Integrated Pest Management software is based totally upon - ANS-1.Scouting for
pests-knowledge pest biology 2.Environmental facts-increase levels of subject crops
3.Era to prevent unacceptable thresholds of pest damage via maximum econmomical
method-financial threshold of bugs, diseases or weeds
4. Lowest possible threat to people , belongings, resources and surroundings-socially
acceptable manipulate measures
auricle - ANS-may or now not be present, very in duration. Lengthy auricle might also go each
other and clasp the stem, as in quackgrass.
Describe soybean aphids and wherein they occur - ANS-pinhead-sized, yellow, smooth bodied,
round bugs at the undersided of soybean leaves
describe the arrival of adult bean leaf beetles - ANS-1. Yellow, green, tan, or study background
colour
2. 4 black spots and black stripes on edges
3. Black triangle always gift at base of wing covers
describe the advent of alfalfa weevil larvae and adults - ANS-1. Larvae-shiny black head
curved frame inexperienced with white stripe
skelotonize have fields look white frosted
2. Adults-mild brown with darker brown stripe alongside center of returned-chew on stems
describe the advent of older armyworm larvae and the damagethey motive on wheat - ANS-1.
Look-1 half inches long, and brown/inexperienced with two orange stripes on every facet
2. Harm-seedlings get chewed to the floor
-circulate in mass and are trying to find out meals and might ruin corn plant life
describe the appearance of potato leafhopper - ANS-green wedge shaped about 1/8 inch
lengthy
describe wireworms and their damage - ANS-1. Apperance:larvae are yellow to reddish-brown,
hard shelled and cord like
2. Damage: tunnel into seeds and seedlings beneath soil degree
epp - ANS-early preplant, carried out 2 or greater weeks previous to planting
, leaf blade hairs - ANS-absent, bushy, hairy at base
ligule - ANS-positioned at the internal aspect of the leaf blade and appears as an extension of
the sheath at its intersection with the blade. Ligules are hairlike or membranous and very in
duration and shape
List three examples of financial thresholds for some insect pests - ANS-1. Black cutworms-3%
or extra of plants are reduce
2. Bean leaf beetle-defoliation reaches 30% before bloom
three. Potato leaf hopper-certain wide variety are accrued per sweep at a given plant height
List elements which can be taken into consideration in determining an financial damage stage,
the range of pest where the value of crop loss from those pests equals the price of controlling
them - ANS-1. Quantity of pests or estimate of the amount of damage
2. Fee of diverse remedy options
three.Anticipated yield
four.Expected grain fee
name three kinds of overwintering, vegative, reproductive systems (propagules) -
ANS-rhizomes, stolons, budding roots, bulbs
put up - ANS-postemergence, carried out after crop and weed emergence
ppi - ANS-preplant incorporated, implemented and routinely incorporated prior to planting
pre - ANS-preplant, applied prior to crop planting. Or, preemergence, implemented after planting
but earlier than crop and weeks emergence
sheath - ANS-enloses the bud shoot and is attached to the leaf blade at the collar
the sheath of maximum grass plants is break up and overlapping
there are four fundamental traits that are used to pick out broadleaf weed seedlings -
ANS-1.Cotyledons: the meals source for the seedling(shape and size vary: opposite)
2.Proper leaves: the ones produced after the cotyledons(shape and shade range greatle)
three. Association of real leaves: change, contrary, or whorled
four. Leaf petiole(leafstalk): attaches leaf to stem(range in duration and hairness or can be
absent)
weeds affect crop manufacturing with the aid of - ANS-competing with plants for water, nutrients,
and daylight, and space.
Decreasing:yield , crop first-rate, and harvest efficiency
