It’s very important to control weeds in a lake or pond due to their many effects on aquatic life. You should therefore consider the Integrated Pest Management, IPM, measures. The IPM requires you to use biological, mechanical and chemical control. Its very advisable to start weed management program to manage dangerous weeds. In this article, I will outline the major ways you require to control the weeds.
Use of biological ways is not complicated and is easy. You can use the triploid grass carp, although fish grass carp are controlled fish species. Before using this method you should have a license. The price of grass carpets are usually determined by the type of weeds which need to be managed and the area covered by the weeds. The triploids should be used regularly to achieve better results. Biological ways helps save cost.
You can also employ mechanical ways to manage weeds. 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. It’s advisable to use mechanical weed control immediately the weeds starts growing in the lake. Quick removal of weeds will stop spreading and save costs.
Use of chemicals is also effective in removing weeds. You should be very careful while using chemicals. Use of herbicides needs experts or authority. Despite the fact that the method is costly, it’s the best in removing weeds. Application of chemicals needs experts since its dangerous. 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. In contrary, the use of chemicals on emerged plants is effectively done during the winter seasons when the plants are not active. You should also consider applying the chemicals only on some portions of the lake and not everywhere. Applying the chemicals on only some sections and then giving it a period of one week will help you prevent poor aeration. The best approach to seaweed control is identifying the weeds and then choosing the best management technique for controlling the weeds. Proper weed control increase aeration in water and helps increase the number of aquatic species and for easy navigation by sailors. You should employ these ways when you need to eliminate seaweeds.
