What are Bolls?
Bolls are part of the plant that holds and protects the seed. They most often occur on cotton and flax plants. Bolls can be damaged by errors or rot, so the plant is unable to reproduce or unsuitable for harvesting.
The word "Boll" comes from the Dutch word bolle , which means "round object". Bolls are generally round or mostly round with narrowing at one end. They are usually solid to the touch and are similar to color to the rest of the plant.
The purpose of Bolls is to protect the seeds until the plant is ready for reproduction. In addition to seeds, Bolls often accommodate soft fibers. It is these fibers that are harvested from cotton and flax plants to form a fabric. It is a process consuming and time -consuming work. Each farmer of cotton and flax faces two main threats: mistakes and rot. Both can affect Bolls plants if the right measures are.
Boll Weevil'sA small beetle that can move in color from yellow to black. These mistakes represent double threats for plants. Adults Boll Weevils eat cotton seedlings and flower buds and female Boll Weevils puts eggs in the foundations of cotton Boll. There is a single egg in each Boll. When the egg hatches, the larvae remain in Boll for one or two weeks and eat it inside.
cotton plants that have been infested with Boll Weevils are produced by a little usable cotton fiber. Boll Weevil can be controlled using pesticides. Scientists have studied cotton breeding plants that are genetically resistant to the Bolel Weevils.
Another main threat to healthy Bolls is rot. Cotton Bolls can rot if there is too much moisture in the soil. Excess moisture can be caused by too much collision, irrigation and overgrowth. When plants are too clospoly create strong canopies that prevent moisture from leakage. This can happen when joining the soilá too much nitrogen.
The best way to prevent boll is to prevent planting. Leaving enough space between plants and staying in the recommended instructions for nitrogen fertilizers allows evaporation of moisture. Fungicides also help prevent rot, but studies have shown that their use is not a cost -effective method of prevention of boll.
