Now let us get some details regarding two types of herbicides, which are selective and non-selective herbicides. Herbicide is a type of chemical that kills unwanted plants, commonly referred to as weeds. Things like weeds can grow super fast and spread over areas that we want our good plants (flowers, vegetables) to seed. So this is where herbicides become handy tools to be used by farmers and gardeners.
Selective herbicides are designed to act against only certain plants. They are able to kill some weeds without doing damage to all plants. For instance, a particular herbicide will kill broadleaf weeds (which has broad leaves) but it won’t kill grass (it has long and narrow leafs), this type is called selective. This is extremely beneficial to farmers or gardeners as it helps them eliminate the troublesome weeds and keep their good plants unaffected.
Then there are the non-selective herbicides when it comes time to talk about targeting. Such herbicides are extremely potent and will destroy any vegetation it comes in contact with. An example of one is glyphosate, which is a systemic, non-selective herbicide that will kill both the weeds you want to remove and any plants you want to keep alive. That can be dangerous if you're not cautious when using it since it'll hurt your nice plants too.
A lot of advantages, or good points, of selective herbicides. One big benefit is that they are more environmentally friendly. Because they only target certain types of plants, they are not a danger to the plants and animals we want to protect. This means less risk in gardens and farms. Moreover, some types of weeds can be quite susceptible to selective herbicides. Non-selective herbicides (ones that kill absolutely everything in your garden) can sometimes be a better solution, but then again, some weeds just remain unharmed!
Non-selective herbicides such as glyphosate are more versatile, in that, they will kill any plant they contact. They are fast, though, and can quickly wipe out whole swaths of vegetation. This is particularly handy for larger jobs, like clearing forests, or large fields. Nevertheless, we should take into account that they are very harmful to nature and surrounding natural wildlife as well so such places must be used with utmost kind of care.
The choice of selective or non-selective herbicide boils down to what exactly you need. Selective Herbicides — If the issue is small with only a few types of weeds, a selective herbicide may be your best solution. It will allow you to target only those weeds without damaging your healthy plants. However, if your garden is a vast jungle of weeds then you might want to use something non-selective.
Here we told you the selective herbicides which are too useful but have disadvantages / cons. The main problem with them is they typically only work for certain types of weeds. In some circumstances, the weeds develop resistance to particular herbicide classes. Now if you follow a single herbicide for instant years, these types of of the weeds will be left in their root form, and the next time around many food products will go up just like they utilized to without reduced influence from your natural herb destructive.
