Effective prevention and control measures for golf course lawn moss

The necessity of moss control
We can see from the habits and hazards of moss: Moss is a major scourge on golf courses. It not only affects the maintenance cost of the golf course, for example, its ability to compete for nutrients is much greater than that of grass, but also affects the air and water permeability of the soil. In addition, it hinders guests from playing golf and affects the landscape of the golf course. When the damage is serious, it can cause large areas of lawn to wither, destroy the golf course, and endanger the operation of the golf course. Therefore, its management and removal is a long-term concern for golf course lawn maintenance.

Prevention and control measures for golf course moss
The occurrence of moss is not only related to soil conditions, but also to climate conditions and fertilization levels. We must start with management. When moss appears on the lawn, it must be combined with pesticides for comprehensive prevention and control.
Common methods of preventing and controlling moss on the golf course include: spreading lime. The disadvantage is that it damages the lawn and damages the physical and chemical properties of the soil. In particular, it changes the pH of the soil and makes the soil alkaline. However, the suitable soil for lawn plants is acidic, which reduces the resistance of the plants. Reverse nature. The second is the use of copper-containing agents. Long-term use will cause the accumulation of heavy metal copper ions, change soil properties and the structure and composition of root zone microbial communities, and affect soil root zone properties and soil quality.

Currently, the internationally accepted prevention and control methods and measures are: applying biological moss control drugs to control moss; applying fertilizers that can strengthen turf grass, enhance the plant’s ability to resist moss, and increase the water and air permeability of the soil. Specific effective measures are as follows:
1.1 Prevention in advance
Mainly refers to the correct implementation of various management measures in daily maintenance and management, and accurate grasp of the implementation time of each measure (especially March-November each year) and implementation methods (advance medication prevention), so as to keep the turfgrass in a healthy state. The growing state reduces the possibility of being infected by moss. Secondly, prevent it through the daily application of some environmentally friendly biological control products, and do not wait until the moss becomes serious before remediating it.
1.2 Improve soil structure
Lawns are often trampled, which will compact the soil and affect the growth of the lawn root system. By drilling holes and applying soil microbial activator Bomaxi, etc., the air permeability of the soil can be improved and the resistance of the lawn to moss infection can be improved.
1.3 Adjust soil pH
The most suitable soil pH for turfgrass is weakly acidic to neutral, so the pH should be adjusted according to soil conditions. On acidic soils, hydrated lime can be applied to increase soil pH. On alkaline soils, gypsum, sulfur or alum can be used to increase acidity to provide a suitable soil pH for the growth of turf grass.
1.4 Reduce shade
By pruning local shrubs, cut off overly dense branches to facilitate ventilation and light transmission, reduce shading of turf grass, and improve the growth environment of turf grass.
1.5 Scientific fertilization and reasonable watering
Fertilize scientifically and rationally, reduce the use of nitrogen fertilizers, use phosphate fertilizers appropriately to promote root growth, reduce the pH value of surface soil, and prevent moss infection. It is necessary to irrigate properly and avoid improper watering to promote the healthy growth of lawn grass.
1.6 Reasonable pruning
Moss and turfgrass compete with each other for sunlight and nutrients. Excessive pruning weakens the power of turfgrass and facilitates the growth of moss. During the rainy season from April to August, moss control products should be applied promptly after pruning to inhibit the growth of moss.
