Double Mode of Action

When deer, looking to feed, approach a treated plant, they are repelled by the smell of the product.

If the deer succeed in biting the plant the taste will deter them from feeding any further.

Industrial Forestry

TRICO® PRO is a product that assists the large-scale forester to reach their reforestation targets. In areas with high browsing pressure, this product can protect tree species that are preferentially selected by deer, elk and moose.

TRICO® PRO’s long-lasting protection reduces the effort and expense when compared to fencing strategies 

Nursery Trees

Discouraging browsing by deer, elk and moose can also conserve native species in conservation settings.

Applying TRICO® PRO in the nursery ensures your customers trees are protected from the moment they are planted while saving application costs in the field.

TRICO® PRO is suitable for spring and autumn planting.

Corn growing protection

TRICO®  ensures that crops can grow undisturbed.

Deer damage of agricultural crops has increased in recent years. Red and roe deer will browse on emerging corn crops.

Ultimately, this will lead to missing plants, an uneven crop and will influence yield.

An application of TRICO® over the full field or at least 70 foot wide perimeter around the field will discourage deer from browsing.

Grape vine protection

TRICO® protects vines against game browsing.

In vineyards, early plant growth is especially susceptible to damage caused by deer.

Game browsing can retard plant growth, which can have long-term effects on yield and quality. In severe cases, a young vine may require replanting.

Using TRICO® any time before flowing to deter deer from browsing the foliage.

Soy crop protection

Due to its high protein, content soy crops are a particular favorite for foraging deer.

Growers in high deer density areas have switched to other crops, like sorghum, to minimize the ingress of deer.

TRICO® allows those growers to move back in to Soybean production.
