Corteva launches herbicides based on aminocyclopyrachlor

Corteva Agriscience has launched herbicides based on the aminocyclopyrachlor molecule in Brazil. In celebration of the 65th anniversary of the Pastagem Line, the company presented two products with the commercial names Navius ​​and Juvix.

The new herbicides expand Corteva's portfolio with a focus on effective weed control, ease of application and increased profitability.

According to Rodrigo Takegawa, leader of Corteva's pasture line for Brazil and Paraguay, the new technology eliminates weed competition and improves pasture quality, favoring meat and milk production without the need to open new areas.

Aminocyclopyrachlor (C8H8ClN3O2, CAS 858956-08-8) acts as a hormonal regulator. It interferes with the development of undesirable broad leaves. The molecule presents systemic translocation, rapid absorption by leaves and roots, low volatility and reduced dose. All this with high selectivity to forage grasses.

Navius: granulated formulation

O Navius ​​herbicide (click here to learn more) It combines aminocyclopyrachlor and metsulfuron-methyl. According to the company, this is the first herbicide with this formulation in the category. It is odorless and dissolves easily. Its application is recommended for areas with established grass pastures and herbaceous, semi-shrub or shrub infestations.

In localized foliar application, it is effective against species such as purple fish-eater, cape-bode, milkweed and cow's foot. In total area application, it controls hot grass, white stinker, white gervão and guanxuma, among others.

The product requires a low dose per hectare. In tests, it showed better results than the competitors analyzed even with a lower amount of active ingredient. It acts as a booster for Corteva's own Ultra-S and XT-S technologies, allowing the dose of these complementary herbicides to be reduced without loss of performance.

Juvix: practical handling

On the other hand, the Juvix herbicide (click here to learn more)  It comes in a liquid formulation and can be applied to the stump of the plant after mowing. The product stands out for its convenience and increased operational productivity. With continuous use throughout the year, it eliminates the need to dig the soil to control deep roots.

Its use only requires cutting the plant up to 10 centimeters from the ground. This reduces the application time by up to three times compared to the traditional method, reports Corteva.

In difficult-to-control species such as cagaita and leiteiro, Juvix achieved control rates of up to 92%. Market standards did not exceed 83%.

The herbicide is registered for use against species such as miroró, cabriteiro, cipó-prata and lixeira. Its fast and effective action increases the pasture stocking rate and improves animal performance, as they tend to avoid areas infested with large weeds.
