Disease and fungus growth can be a big concern for lawns and landscapes but aside from that another troublesome issue are the threat of nematodes. Nematodes can deliver some big damage to turf where they are found and if not treated quickly you may end up seeing a lot of dead plant-life. Thankfully, there is an active ingredient that not only deals with common fungus issues which may occur on landscapes but can also kill destructive nematodes. This active ingredient is iprodione.

On this page we will give you an overview of iprodione, its origin and why it works so well to eliminate fungi and nematodes. Here you can also shop the fungicide products we have in stock which contain this iprodione. 

What is Iprodione?

Iprodione (3-(3,5-Dichlorophenyl)-N-isopropyl-2,4-dioxoimidazolidine-1-carboxamide) is a contact and locally systemic fungicide and is designed to protect a variety of agricultural crops such as almonds, grapes, peaches, potatoes, rice, berries, onions, peanuts, lettuce, golf courses, lawns, and ornamentals. There are currently 70 tolerances for iprodione.

Iprodione was first registered in the U.S. in 1979 as a fungicide.  It has also been recently used as a nematicide to control nematodes in some countries.

Iprodione has a number of different formulations including liquid, dry flowable, wettable powder, and granular. Iprodione fungicide has been applied through a variety of methods such as by aircraft (fixed-wing and helicopter), airblast sprayer, chemigation, groundboom, high- and low-pressure hand sprayers, backpack sprayer, and tractor-drawn spreader.

How Does Iprodione Work?

The mode of action of iprodione is that it inhibits DNA and RNA synthesis in the germinating fungal spore was well as inhibiting the enzyme NADH cytochrome c reductase, thereby preventing lipid and membrane synthesis and ultimately mycelium growth.  

Iprodione is a systemic fungicide. It slowly works its way up through the plant roots and into all the parts of the plant. Some of the common fungal diseases iprodione has successfully been able to control include: Fusarium, Red Thread, Dollar Spot, Anthracnose, Leaf Spot and Rust.

How is Iprodione Used?

Iprodione is successfully used on amenity turf such as golf courses, bowling greens, lawns, sports stadia, cricket pitches and tennis courts. Crops that can be treated with iprodione include brassica, brussels sprout, bulb onion, cauliflower, lettuce, oilseed rape, raspberry, salad onion, strawberry, tomato.  It can also be used for ornamental plant production, both when growing and from seed.


How Safe Is Iprodione?

Iprodione has low toxicity for mammals, birds, bees, insects, and earthworms. According to the EPA, iprodione is classified as a category III which makes it safer than most of the fungicides we carry.


As we suggest when handling and applying any of our chemical products, we highly recommended wearing personal protective equipment required to lessen the risks of inhaling, ingesting or coming in contact with the skin. The minimum PPE suggested when handling iprodione based products includes chemical resistant gloves, eye protection, and long sleeved clothing. Please make sure to follow the label instructions for the proper directions in applying the product and knowing what safety measures to apply.
