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. TRICO® protects crops and yield.

Vineyard 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 deters 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.
