Nemacide (also nematicide, nematocide) – a chemical to eradicate or kill nematodes. Parasiticide – a general term to describe an agent used to destroy parasites. Pediculicide – an agent that kills head lice.
Generally, avoiding tree stress and maintaining an overall healthy tree is the most ideal way of avoiding the canker. Avoiding any physical injuries to the trunk, limbs, or roots is important as these injuries can disrupt growth processes and xylem/phloem transport. Disruptions to the soil surrounding the tree should also be minimized.
The study of suicide methods aims to identify those commonly used, and the groups at risk of suicide; making methods less accessible may be useful in suicide prevention. [4] [3] [11] Limiting the availability of means such as pesticides and firearms is recommended by a World Health Report on suicide and its prevention.
Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...
Tree spiking involves hammering a metal rod, nail or other material into a tree trunk, either inserting it at the base of the trunk where a logger might be expected to cut into the tree, or higher up where it would affect the sawmill later processing the wood. Contact with the spike often damages saw blades, which can result in injuries, or ...
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
A hypoxic, carbon dioxide-free, metabolically inert gas that is less dense than air is provided for inhalation by confining the continually flowing less dense (than air) gas supply and the head in an impermeable bag which is slightly open at the lower neck, which continuously fills from the closed top down to the slightly open neck.
Robot in a wooden maze. A maze-solving algorithm is an automated method for solving a maze.The random mouse, wall follower, Pledge, and Trémaux's algorithms are designed to be used inside the maze by a traveler with no prior knowledge of the maze, whereas the dead-end filling and shortest path algorithms are designed to be used by a person or computer program that can see the whole maze at once.
