PDF-Defoliation

The variation of crown condition expressed by the density of the foliage is mainly the result of climatic site and tree related factors Moreover defoliation may be caused by a number of bioti. These factors vary a great deal during the season and the choice of mate rials and application rates varies as well The appropriate time for defoliation depends mainly on crop maturity and the desired harvest schedule Timing for Defoliant Applicatio S Department o Agriculture James A Christenson Director Cooperative Extension College of Agriculture and Life Sciences The University of Arizona The University of Arizona College of Agriculture and Life Sciencesis an equal opportunity employer author Cooperative Extension Agriculture, James A.

Machinery used to Harvest Cotton. Using a cotton picker; or spindle picker to harvest your cotton will result in a large round bale of cotton lint mixed with seed, which will be ready for further processing. As the cotton picker traverses the field rotating rows of barbed spindles in the machine will remove the seed-cotton, as the entire boll from the plant. This will then transfer to the doffer which rotates in the opposite direction and blows; or doffs; the cotton to a collecting basket. Once the basket is full the seed-cotton is transferred to the round baling section or module builder which acts like a large trash compactor that compresses the seed-cotton into a large cube. This can then be stored in a warehouse to await cleaning with a cotton gin.. 2017 Forest Health Workshop – Walker, MN. Mike Parisio – NW Region Forest Health Specialist.
