Answer:
Some practices from the recommended list of physical/cultural control that you could do year-round to help control pests are as follow:
1. We can use those plant species that are more competitive. These plant species include release of chemical toxins that suppress other plants and insects.
2. Use of large Hight quality seeds.
3. By using narrow spacing in row and increasing seeding rate.
4. By using shallow seeding technique which allow desired plant species to grow and develop faster above the surface of soil.
5. By ensuring that our plant species is perfectly placed in that growing environment which is optimized with every specs.
6. By rotating the crops
7. By rotating plant species with different growing cycles and seasonal cycles.
8. By rotating herbicides with alternative modes of action to delay the herbicide resistance development.

A.
The aim of a tax on a valuable resource, in this case residential water use, is to reduce wasteful practices. In this case the county is considering a special tax when residential water use is ABOVE a certain amount. This is an effective mechanism to reduce wastage by causing high users to incur more cost. Everyone will still pay for their water consumption in the normal way (typically by a $/unit cost), however the tax will take effect when the residential water consumption reaches a certain point. This penalises high users of water by forcing them to pay more for a valuable resource. Note that essential services like energy and water are often subsidised in society. This means that we do not pay the true cost associated with the use of the resource. Setting a tax that applies to those that consume over a certain threshold helps to reduce wastage of an undervalued essential resource such as water or energy.
