GUARANTEED PASS
Defoliation - ACCURATE ANSWERS✔✔ Leaf loss or leaf absicisson.
In cotton production, it usually refers to leaf loss associated with
application of a chemical that injures the leaf. Defoliation can also occur
through natural leaf maturation and senessence, particularly with cooling
weather after boll development
Desiccation - ACCURATE ANSWERS✔✔ acclereated drying of plant
tissue
Harvest Aid Chemical - ACCURATE ANSWERS✔✔ chemicals with
various modes of action that facilitate machine harvest by influencing
boll opening, reducing the ammount of foilage retained on plants at
harvest, speeding tissue dessication, and controlling regrowth
List reason for using harvest aids - ACCURATE ANSWERS✔✔ -
Prepare cotton for harvest in a more predictable and timely manner
-Help straighten lodged plants for better drying and picking
-Reduce the number of high-moisture-content green leaves, which
otherwise would lower fiber grade
, -Can stimulate and enhance boll opening and increase yield and quality
-can reduce leaf trash and other impurities at harvest and in the gin
-improve the uniformity of boll opening and maturity required for
mechanical harvested cotton
-reduce the chances of fiber damage due to high water content in
modules of harvested cotton
-Reduce lint losses associated with excessive need for cleaners during
ginning when cotton has higher trash content
-Promote a more uniform preperation and condition of cotton that can
improve the speed of ginning
-Improve efficency in use of labor and equipment for harvest
-Allow havrest during more favorable conditions
-Reduce the amount of time lint is exposed to late season insect pests,
under certain conditions
-Allow more time to prepare the ground and equipment for the
subsequent crop
