Questar™

Fungicide

The new and unique solution to flexible and robust cereal disease control.

Questar™ is a new fungicide for the control of Septoria tritici, brown rust and yellow rust in wheat, durum wheat, rye, triticale, and spelt.

Questar is broad-spectrum fungicide containing Fenpicoxamid, more commonly known as Inatreq™ active. 

Inatreq active offers a new and unique site of action for curative and persistent protection against all Septoria strains. Using Corteva’s patented i-Q4™ technology, it provides near 100% leaf coverage and is highly flexible in application, delivering robust protection so you can secure your yield and the future of your farm.

 

Characteristics of Inatreq active:

  •  • A new site of action for broad spectrum disease control in cereals.
  •  • It offers robust control of Septoria, including isolates resistant to other sites of action.
  •  • It is an excellent broad-spectrum product as it also offers control of yellow and brown rust.
  •  • Patented i-Q4 technology brings flexibility to applications by helping compensate for the spray settings such as the use of low drift nozzles.

About Questar

Best Use Advice

  • Questar may be used on all commercial varieties of wheat, durum wheat, rye, triticale and spelt wheat.
  • Ideally apply at T2 to see maximum yield benefits, but Questar could alternatively be applied at T1 if preferred.
  • Questar will give the best results before the disease has become established in the crop, but offers outstanding control of Septoria, yellow rust and brown rust both with persistent protectant and curative activity.
  • Questar offers broad spectrum, superior disease control which leads to longer green leaf retention and improved yield.
  • Rainfastness is 1 hour for Questar, this is mainly down to the patented iQ-4 technology.
  • The unique iQ-4 formulation empowers Questar and improves spray retention, spread, penetration and uptake. The use of low drift nozzles does not negatively affect the performance of Questar.
  • Questar must always be used in mixture with a product with a different mode of action at a dose that offers robust control.

Resistance Management

Questar™  must always be used in mixture with a product with a different mode of action at a dose that offers robust control.

Do not apply more than one application of any product containing Inatreq (fenpicoxamid) to any cereal crop in the same year.

Questar should be used in accordance with the instructions for use for the target disease at the specific growth rate indicated.
