There are several approaches to pond management. This article will discuss Integrated Plant Management (IPM), Aquatic Herbicides, Biological control, and Cultural power. Each of these approaches has its pros and cons and will be discussed in detail. For example, IPM encourages plants to grow in a healthy environment, whereas Aquatic herbicides kill them. On the other hand, the latter approach is less effective and is more costly.
Integrated Plant Management
Plant Control combines chemical, biological, and mechanical methods with a holistic approach to pond management. Physical methods include limiting nutrient inputs and improving oxygen concentrations. Chemical methods include weedkillers and tying up phosphorus. Biological methods involve the use of beneficial bacteria and enzymes that help tie up nutrients. These methods can also prevent erosion. Integrated Plant Control helps reduce the risk of aquatic plant infestation and helps preserve the natural habitat and recreational value of a pond.
An effective IPM program must incorporate the best available control methods, incorporating site-specific strategies for each pond. The theory behind IPM is not to eliminate pests, but rather to keep their populations balanced. Using a variety of biological control methods, the goal is to minimize the detrimental effects of pest populations and mitigate the development of pesticide resistance. Integrated Plant Management is a highly effective approach for ponds and lakes.
Aquatic herbicides
One method of removing unwanted weeds in a pond is with aquatic herbicides. Aquatic herbicides have no toxicity to fish and other pond animals. However, some herbicides come with restrictions for swimming and livestock. Follow label instructions carefully to avoid causing harm to fish or other animals. You should also read labels and follow precautions to prevent pond pollution. The danger of aquatic herbicides is low compared to those of other types of pesticides.
The label of an aquatic herbicide will list its dosage in acre-feet. An acre-foot is the volume of 326,000 gallons of water. You can calculate the volume of water in your pond by multiplying the surface area by its average depth. You can also determine the amount per acre-foot using the formula below. Aquatic herbicides are also available in a granular or liquid form.
Biological control
Biological control involves introducing beneficial organisms to a pond. These organisms control nuisance plants and aquatic plants, such as algae and weeds. Some of these organisms are naturally occurring and are beneficial for your pond. These include pond snails, water lilies, and water hyacinths. One of the most troublesome pond problems is the presence of unwanted aquatic vegetation, or ‘duckweed’. There are many methods for controlling this problem, including biological fish that eat the plants, chemical treatment, beneficial plantings, and mechanical means such as dredging, pulling, cutting, and raking. Biological control is usually the better long-term solution, although you may need to invest in a sterile grass carp for a while to get rid of the weeds. Chemical control involves the use of aquatic herbicides or algicides, but these can be expensive and require extensive attention.
Cultural control
One of the most effective ways to keep your pond clear is by controlling phytoplankton blooms. These blooms help feed the aquatic plants, but they can also decrease the amount of sunlight reaching the bottom of the pond. A healthy phytoplankton population can also help control the water’s turbidity, or the amount of suspended sediment in the water. It also discourages the establishment of nuisance plants like rushes and weeds.
Another method of controlling aquatic plants is by introducing animals and plants to the pond. Introduce some fish and small animals to the pond to control the plants that thrive there. This method is also helpful if you do not have a drain for your pond. However, if you can’t find a drain in your area, you can use a water pump to control the water level in your pond.
Inversion
The Inversion approach to pond management focuses on preventing the growth of algae, while the aeration method removes the muck from ponds. It works by circulating the water through the pond, while keeping the level of dissolved oxygen high. This process saves you money and time by reducing the use of chemicals. H. Inversion is a natural process that occurs in spring and fall. The colder water at the surface carries more oxygen than the warm bottom water. This process drives off the toxic gases from the bottom layer and revives the aerobic bacteria population. Bacteria in a pond help in the decomposition of organic litter. Inversion is one of the most popular pond management techniques, but it does require some practice.
