BT 04

Stable yields with intensive technology

The BT 04 sunflower hybrid from the breeder RAT is a selection solution for farmers focusing on the Clearfield (Euro-Lightning) system. Under modern conditions, where field weediness becomes a critical factor, choosing material with genetic resistance to imidazolinone herbicides becomes a necessity rather than an option. BT 04 allows for effective control of a wide range of weeds, including problematic species, without compromising crop development rates.

Biological potential and adaptability

The vegetation period of the hybrid ranges from 100 to 120 days, making it a versatile tool for most climatic zones. Such flexibility allows for planning the sowing campaign with regional weather risks in mind. An important indicator is the oil content of the seeds, which varies from 45% to 50%, ensuring high market value of the harvest when sold to oil extraction plants.

Phytosanitary reliability

The breeding work on BT 04 was aimed at creating a barrier against the most common pathogens affecting sunflower crops. The hybrid demonstrates high resistance to a complex of diseases that can significantly impact yields:

• Alternaria leaf spot: reliable protection of the leaf apparatus.
• Phomopsis: prevention of premature stem drying.
• Rots (white and gray): minimization of losses under unfavorable weather conditions.
• Powdery mildew: maintenance of photosynthetic activity at all stages of vegetation.

Russian selection by RAT in the BT 04 model focuses on resilience. It is a workhorse that compensates for certain technical nuances while maximizing its potential when crop rotation and proper soil preparation are followed. Due to the combination of herbicide resistance and immunity to major diseases, this hybrid is a balanced choice for farms striving for predictable economic results.
