Here at Solutions Pest & Lawn, some of the active ingredients in our herbicides can be very versatile. One such active ingredient that seems to do it all is diuron. Diuron is used as a herbicide on a variety of both crop and non-crop areas. It is also used as a mildewcide in paints and stains, and as an algaecide in commercial fish production

Solutions Pest & Lawn has a nice selection of herbicide products in stock which contain diuron and we highly recommend this product to our customers. On this page you can learn some historic facts about diuron, how it works and its benefits. You can also access this page to shop our entire line of products which contain diuron

What is Diuron?

Diuron is the trade name for DCMU (chemical name:3-(3,4-dichlorophenyl)-1,1-dimethylurea) a substituted urea compound registered for use as a herbicide to control a wide variety of annual and perennial broadleaf and grassy weeds on both crop and non-crop sites. Diuron was first introduced by Bayer in 1956 and since 1967 has been used in the USA. 

Diuron is used on numerous crop sites such as forage crops, field crops, fruits, vegetables, nuts, and ornamental crops. In non-crop applications, diuron is used on industrial sites, on rights-of-way, around farm buildings, and on irrigation and drainage ditches.

In its original form diuron is a white, crystalline, odorless solid. It is stable towards oxidation and moisture under conventional conditions and decomposes at 180-190 degrees C. The chemical does not exhibit any unusual handling hazards.

Diuron is sold in a variety of different formulations such as a wettable powder, granular, flowable, pelleted/tableted, liquid suspension, and soluble concentrate formulations.

How does Diuron work?

The mode of action of diuron is that it is a very specific and sensitive inhibitor of photosynthesis. It blocks the plastoquinone binding site of photosystem II, disallowing the electron flow from where it is generated, in photosystem II, to plastoquinone. This interrupts the photosynthetic process in the electron chain and thus hinders the ability of the plant to turn light energy into chemical energy (ATP sugars and reductant potential).

Diuron only blocks electron flow from photosystem II, it has no effect on photosystem I or other reactions in photosynthesis, such as light absorption or carbon fixation in the Calvin cycle.

However, because it absorbs electrons oxidized from water in PS II, the electron "hole" of PS I cannot be satisfied, effectively shutting down "linear" photosynthesis by blocking the reduction of NADP+ to NADPH. At the same time, it was found that diuron not only does not inhibit the cyclic photosynthetic pathway, but, under certain circumstances, actually stimulates it.

Diuron 80df Herbicide-  Diuron 80 DF Herbicide is designed as a dispersible granule for control of weeds in specific crops and for non-selective weed control on non-crop sites. Diuron can be used as a pre-emergent as well as a post-emergent.


Diuron 4L Herbicide- Diuron 4L Herbicide (generic Karmex IWC 4L) by Alligare LLC is formulated to target annual and perennial grasses and herbaceous weeds in crops. Diuron 4L may also be used for pre-emergent and post-emergent control in non-crop areas.


Mojave 70 EG Herbicide -  Mojave 70 EG Herbicide (generic Sahara) is a granule imazapyr diuron herbicide that is mixed with water for pre-emergent and post-emergent control of listed grasses and weeds in areas where bareground is desired. Once sprayed no vegetation will grow for up to 1 year.


Is Diuron Safe To Use?

Diuron has a low toxicity for mammals, as doses above 3,4 g per kg body weight are needed to induce acute toxicity. Some fish and marine invertebrate species experience acute toxic effects at diuron concentrations above 4,3 mg/l and 1 mg/l respectively. Algae are most vulnerable to the herbicide, it can be toxic for some algae species at concentrations of only 5 µg/l.


While diuron is safe to use, we do recommend exercising caution when handling diuron products (or any other chemical we have in stock) to wear protective safety equipment such as a protective mask, gloves and goggles as well as long sleeve clothing to ensure you will be safe. Please use the product according to the labels directions for proper safety measures.
