Plant diseases are considered the most common constraints to increase productivity in agricultural crops. Farmers, gardeners and nursery growers of willow tree should have a basic knowledge of the different agent causing the defect. In this manner, there is a high probability of preventing and controlling fungi attacks to plants. Top of the list stimulating the ailment is the Venturia fungus, which is known to induce a major damage to plants.

Here are 5 steps in preserving a willow tree from Venturia fungus attacks:

Step 1

Awareness of the plant diseases caused by fungi. The best defense against this venturia fungicide epidemic is to have full knowledge of the infections produced by it. Most common occurring plant diseases are: Cankers (woody plants), Damp off (all type of plants), Root rots (all type of plants), Seed decay(all type of plants ), Wilts (all type of plants).

Step 2

Proper plant selection and placement. To help withstand the infection, plants should be checked carefully for signs of stress or injury to ensure that all placements in the landscape are healthy. Wounds, leaf scars, ground cracks and lenticels are the primary target of venturia fungi to initially colonize on it and move downward to a branch and sapwood.

Step 3

Growers should consider environmental stress in planting post. Most external factors like heat, drought and compacted soil are uncontrollable, but in some way can be avoided. Breeders should refrain planting in areas that are condensed by construction, overly wet soil or suffers from poor drainage. In the places where there is extreme heat during summer months, trees should get adequate quantity of water. Venturia fungus is very susceptible with this kind of conditions and should be corrected before and after seeding.

Step 4

Growers should observed proper cultural practices. They should practice proper pruning techniques in order to avoid large pruning cuts. In doing landscaping, due care must be done in using equipments, such as lawn mowers to avoid injury to trees and shrubs. Further, handle plants carefully during seeding to put off damage to roots, trunks, branches, stems of trees and shrubs; Thus, preventing plant tissue from venturia contamination.

Step 5

Monitor plants carefully for signs of infections, proper nutrient availability and sanitation measures. Diligently oversee symptoms of diseases and other agent that can injure plant and predispose tissue to venturia fungus infection. An appropriate nutrient placement is essential for healthy trees and shrubs. Always refer to the soil test report or tissue analysis before fertilizing woody shrubs and trees. Pruning out dead wood and disinfecting pruning tools with rubbing alcohol between cuts is very important to prevent the spread of venturia fungus to an area on the branch that is healthy.


Therefore, opportunistic plant pathogens like venturia fungus only cause damage on plants that are stressed and injured. Hence, it is important to remember that under ideal growing conditions, trees and shrubs are commonly able to fight infections caused by venturia fungus.
