What weed does 2 4-d kills?

2 4-D or 2,4-dichlorophenoxyacetic acid can kill most terrestrial and aquatic broadleaf weeds (except most grasses such as cereals, lawn turf, and grassland), and also unwanted vegetation by causing uncontrolled growth in them.

It can control broad-leafed weeds in pastures, orchards, and cereal crops such as corn, oats, rice, and wheat without harming them.

It is also the killer of some unwanted weeds that we often fight against such as dandelions, plantain, clover, and chickweed.

First, measure your garden area using the formula: width multiplied by length.

In case your garden is not completely square, divide it into smaller squares or rectangles, apply the above method, and then add them up.

1. For Backpack or Pump sprayers

You can mix pesticides in the same proportion as mixing 2.5 ounces of 2 4-D to 1 gallon of water for 400 square feet of garden land.

It means that if your yard is 1,200 square feet wide, you should mix about 7.5 ounces of 2 4-D to 3 gallons of water.

Pesticides you spray on the grass should be just enough. You should not spray too much as the extra pesticides will seep into the soil.

2. For Horse-end bottle sprayers

For about 2,500 square feet of garden land, you should set up to deliver 2.5 ounces of herbicide per gallon of water with up to 16 ounces of 2 4-D in the reservoir. Do not add water to the reservoir because the sprayer will automatically mix the chemical with water.

For 1,000 square feet of yard, you should hold 6.5 ounces of concentrate.

3. For spot treatment

You can mix 1.5 tablespoons of concentrate in half a gallon of water, then fill it in a handheld spray or a misting bottle to spray the small areas or the specific weed you want to eliminate directly.

When to apply 2 4-d?

Depending on the type of plants in your garden, the timing of spraying will also vary. We can divide it into three typical stages: Before planting, when the crop has grown to a certain extent, and after harvesting.

It also depends on the seasons. Herbicides are usually sprayed in the spring and autumn, and when the grass is still small. If the grass has grown too much and taller, physical measures will be more effective than chemical methods.

Early spring is arguably the best time to spray herbicide with appropriate weather conditions. The grass will not die as soon as you spray. Usually, you will see results after two days.

And if you spray before planting, you should wait for 4 to 6 weeks before starting to plant crops to avoid affecting your crop quality.

Below we will give specific instructions for a few common crops.

1 Postemergence
up to 3 Preharvest (not apply for sweet corn)
Hops 1 pint Post-emergence
Rice (not for use in California) ½ to 2 Apply 2 to 4 weeks before planting.
1 to 2 Post-emergence (when rice is in the late tillering stage and at the time of the first joint development)
Soybeans ¾ to 1 Apply not less than 15 days before planting.
> 1 to 2 Apply not less than 30 days before planting.
Strawberries 2 to 3 pints Apply in early spring or right after the last picking.
Sugarcane 3 Preemergence (before cane emerges)
3 to 4 Post-emergence (after cane emerges)

FAQs

After about 2 days you will see the result.

Conclusion

Now you know already how much 2 4d to use for a gallon of water. I hope these tips can help you and your garden. Or, you can also refer to the instructions for use in the vial you buy to determine the most accurate and appropriate dose.

And one more important thing is that chemicals are harmful to us and your pets, so don’t forget to make sure you take precautions and keep your pet safe when spraying.
