Types of Herbicides For Specific Plants
You might be wondering why weed inhibitors are called herbicides.
Actually, weeds are any greens that grow out of the place. It means grass, herbs or any plant hampering the activity of the main plant, so the chemical against them is popularly called ‘herbicides’.
Generally, herbicides are categorized based on the mode and time of application and how they work on the weed.
Mode of application
- Contact: These herbicides work by directly contacting the leaves and stem of the target plant, causing them to wither and die. They are often used to spot-treat individual plants.
- Systemic: Mostly used to control deep-rooted perennial weeds. The plant absorbs herbicides and transports them throughout, including the roots.
Time of Application
- Pre-emergence: Applied before weeds emerge from the soil after planting the main crop. Used in lawn care to prevent the growth of weeds like crabgrass.
- Post-emergence: Incorporated in the soil after the weed seedling appears
- Pre-plant: Mixed in the soil before even sowing the plants
Based on Specificity
- Selective Herbicides: Target specific weeds, either broad-leaf, grass or sedge, while leaving others unharmed, Popular in agriculture
- Non-selective Herbicides: Unlike the above, the non-selective ones restrict the growth or kill all the green in contact with the chemical, including your grown plants.
Factors to Consider When Choosing Herbicides
Before anything, you must consider the type of weeds you are working with when choosing the best herbicides for your plants.
Also, the plants grown in your garden, like marigolds, cosmos flowers, and jasmine, each have different weeds bothering them.
Weeds may be either broad-leaf, grass, or sedge, categorically differing in lifecycle. Simultaneously, their treatment differs.
Similarly, the formulation of herbicides and their active ingredients vary per their target weeds. The active ingredient in a herbicide is the component that kills the weeds.
Look below for the factors you need to consider.
- Correctly recognize the target weed.
- Identify the life cycle of the problematic weeds, whether annual, biennial, or perennial, to choose the best herbicide.
- Looks out for the active ingredients effective against the specific weed you want to kill or suppress.
- Know the weed’s garden history to check whether they are herbicide resistant.
- Check the soil type and pH as it affects the crop injury potential of the herbicides and the residual effect on the subsequent crop.
- Compare the cost of different herbicides with the same ingredient to make it cost-effective.
Pro Tip: Follow the manufacturer’s instructions carefully to ensure safe and effective use.
