Phydura All Natural Herbicide

Phydura All Natural Herbicide


Shipping fee is included (within the contiguous US).  Phydura™ is an OMRI listed non-selective herbicide made from natural, biodegradable ingredients: clove oil, lactic acid, potassium oleate, vinegar, and water for herbaceous broadleaf and grass weeds including: Garlic Mustard, Burdock, Dandelion, Clover, Crabgrass, Queen Ann's Lace, Pigweed, Velvet Leaf, Ragweed, Quack Grass, Leafy Spurge and more!

Kills annual weeds within hours; perennials may need 2 or more applications to kill the roots. Phydura™ is safe around (but not on) trees, shrubs and water.  Phydura™ is a non-selective contact weed killer; it will control anything it comes in contact with, but complete spray coverage is needed (enough to wet the plant, but not to the point of run-off). Phydura™ works best on actively growing plants in full sun and air temps above 60 degrees; the warmer, the better.

How much Phydura™ do I need? 
For young or small weeds, mix one part Phydura™ to 3 parts water (3:1 ratio). Spray entire plant.
For larger or older weeds, mix one part Phydura™ to 2 parts water (2:1). Spray entire plant. 

If you want to kill off turf grass: mix 3 parts water with 1 part Phydura (3:1). One quart product will make 3 quarts of spray. LIkewise, the 2.5 gallon product will make 7.5 gallons of spray. For a spray application of diluted Phydura™ on turf you would need approximately 2 gallons per 1000 sq ft. (90 gallons/acre). So then, 0.67 gallons (86 oz.) of the undiluted Phydura™ needed per 1000 sq ft.

Although it is safe to enter a Phydura™ treated area when the spray has dried, we suggest waiting 24 hours before sowing seed or transplanting.

Keep the concentrate out of reach of children and pets as it can cause eye irritation. As with any spray treatment, wear safety glasses and gloves when applying.  Download the SDS (Safety Data Sheet).

Ingredients: Active = Citric Acid (32%), Clove Oil (8%), Malic Acid (10%)  Other =  Lactose, Oleic Acid and Water (50%).

4 Questions asked on Phydura All Natural Herbicide

Q Fred • April 19 Does Phydura kill the plants to the roots?
A Prairie Moon • April 21 Hi Fred. Yes, but, depending what you are wanting to remove, it may need a few applications. I wouldn't suggest it for extremely invasive woody and vine species like Buckthorn, Asian Bittersweet, Kudzu, Honeysuckle, etc. It's best on herbaceous plants.
Q Sandra • May 18 Hi, how long can I use a jug of Phydura, does it loose its effect if stored for a longer time? Thanks!
A Prairie Moon • May 20 Hi Sandra. If you avoid extremes of heat or cold, under normal conditions, Phydura will be good for 2 years minimum. If it has been sitting for even a short time, it's important to shake the container, and/or mix thoroughly before decanting. For the 2.5 gallon that weighs more, a person could just lay the jug flat on the ground and then roll it over several times. This is much easier than shaking it.
Q Diana • August 13 Does this product kill crabgrass?
A Prairie Moon • August 15 Hi Diana. Yes, it is non-selective so it should kill anything it touches. Crabgrass has a pretty extensive root system, so you may need 2-3 applications.
Q Jane • August 15 Does it kill poison ivy?
A Prairie Moon • August 18 Hi Jane. Yes, i can kill woody vines like Poison Ivy but may need 2-3 applications.
