Its very crucial to control lake vegetation since its very dangerous to navigators and lake animals. You should therefore consider the Integrated Pest Management, IPM, measures. The IPM involves the use of chemicals, natural and machines to control lake weeds. You should consider starting removing aquatic weeds before they cover all pond or lake. In this article, I will outline the major ways you require to control the weeds.
Biological ways are usually less costly and simple. You can use the triploid grass carp, although fish grass carp are controlled fish species. The authority to use fish carps is usually obtained from the state fish and wildlife sector. You need to get authority from the wildlife sector or the government. The value of the triploid depends on the area and the types of vegetation. The triploids should be used regularly to achieve better results. Biological techniques are cheap.
The Mechanical method is also a good way of achieving weed control. Even though mechanical methods are expensive, they are the best ways of managing weeds. If you choose to use mechanical method to remove weeds then you have to remove the remains to prevent them from decomposing which could cause poor aeration in the lake. Its very much advisable to employ this technique before the weeds spread. Immediate elimination of the weeds prevents them from spreading and helps you save time and expenses in the future.
You can also employ chemical treatment to remove weeds. You should be very careful while using chemicals. Use of chemical methods will also need an expert or a licence. Even though the method is costly, it effectively eradicates weeds. You need to hire a professional since when chemical elimination is not done well, it may increase the number of weeds removed and cause poor aeration. Poor aeration causes killing of fish and dangerous disease breakouts and can be homes to parasites.
You can also use the herbicides to remove the weeds. The application of herbicides is effective during the spring season when the temperature of the water is low and the concentration of oxygen is high. On the other side, it’s good to apply herbicides on weeds during the winter because the plants are usually dormant. It’s advisable to apply the herbicides on only some part of the lake and not the whole lake. Applying chemicals to let’s say 30 percent of the pond and then waiting for a week before the next application can help prevent oxygen depletion in the sea. You should initially inspect the type of weeds and then choose a proper strategy to manage them. Efficient weed management will increase the number of fish and make it easy to cruise. This methods are effective in completely eradicating vegetations in the lake.
