What is defoliation?

Defoliation is a term used to describe the removal or loss of leaves. People usually use it for "overall defoliation", which means that all leaves on the plant are lost. The loss of leaves is carried out every year for deciduous trees and can also be artificially caused by humans for various reasons. In some cases, defoliation may be done manually, while in other cases it can be organized with irrigation control and in some situations it can be achieved by chemicals. Defoliation is visible and easier to see the usable part of the crop. It also reduces losses caused by insects, moisture and other problems and facilitates the use of an automated harvesting device, saving the cost of harvesting hand. This type of defoliation is usually controlled with controlled irrigation procedures that promote plants to drop their leaves.

Defoliation can also be performed to check the outbreak of the disease. Some pests infestation can only be controlled by removing the leaves and hopingAt that plants will survive, and the removal of leaves can also be used to control the spread of fungi and other diseases causing organisms. This type of defoliation can be considered the last option when other options have failed.

Chemical defoliation was historically a weapon of war. Determination of defoliants in enemy territory achieves several goals that can further military target. The first is the destruction of food crops that can cause social unrest and lead to pressure to end the war. The second is deprivation of coverage; Without leaves that would be hiding behind or below, enemy soldiers will be easier to identify. This tactic can also be demoralizing, which undermines public support of the war.

In Bonsai Management, Defoliation can be used as a tool to control patterns of some cultivar leaves. This technique is limited to specific cultivars and the plant must be healthy before defoliation. In this case, everyone isThe sheet is cut off with scissors, and the pedikel is left in place to ensure nutrition until the bonsai is recovered. Before defoliation of bonsai, it is important to ensure that the plant is a suitable type and that time is suitable for this practice: plants must be very healthy and it must be the right season, usually late in spring or early summer.
