About Herbicides

Herbicides are effective in killing plants or restraining their growth. The means of herbicides in doing this differs because of the many processes needed to plant life. These chemicals are usually effective when used with proper cultural practiced in a weed management program. The option of the most effective specific mixture differs with economical, ecological and agronomic factors.

Best 4 Gallon Backpack Sprayer Reviews

Herbicides have two types, depending on their effects on plants. These types include selective and non-selective. Selective herbicides are those that stunt or kill weeds in turf grasses without causing too much harm. On the other hand, non-selective herbicides damage or kill all plants when used adequately. However, in certain situations, non-selective herbicides can act selectively if there is an excessive application and a selective herbicide can be phytotoxic. As a result, selectivity is one property of the treatment type as well as the chemical, which is regulated by different factors including the ways of application, time, environment conditions, chemical formulation, the stages of weed and turf grass growth and the dosage.

Chapin 61500 4-Gallon Euro Style Backpack Sprayer For Fertilizer, Herbicides and PesticidesChapin 61500 4-Gallon Euro Style Backpack Sprayer For Fertilizer, Herbicides and PesticidesGET INFOHerbicides can kill weeds such as dandelions, crabgrass and other unnecessary grasses that can damage your garden and lawn. Certain herbicides are manufactured for specific weeds while there are others that can treat a wide range of problems. It is necessary to apply herbicides safely and accurately in order to prevent damage in your lawn and plants and to avoid wasting the product, which is usually expensive. In addition, the exposure of children and pets to herbicides must be avoided because it may cause harmful reaction to the body. Make sure to follow the steps properly in applying herbicide.

The first thing you need to remember is to choose a good quality herbicide sprayer that has an adjustable nozzle. Usually, pump sprayers are available in one and two-gallon sizes, which can be purchased in hardware shops, nurseries and home supply stores. Choose a pump sprayer that can be easily lifted when full.

You have to determine the size of the area you have to treat so that you can identify the amount of herbicide you need to prepare. Remember that depending on the size of your sprayer, you may need to prepare more than one batch to treat the whole area.

Make sure to read the label of the herbicide carefully, especially the emergency instructions. Though it is necessary to know the mixture of the right amount and the number of times of application, you also need to know what you have to do if ever the chemical comes in contact with your skin or eyes. When applying chemicals, it is important to wear proper clothing such as long-sleeved shirt, long pants and a hat. Gloves are needed to protect your hands and shoes to protect your feet.

According to the instructions given, mix the herbicide and spray on the weeds directly and thoroughly. Make sure to avoid applying herbicide on your garden plants for it may damage or kill them. It is better to choose granule or powder herbicides that can be combined with fertilizers and other kinds of treatments. These herbicides have longer effects and are safer to use. You also have an option to use organic herbicides that are friendlier to the environment.Article Source:
