Proline East

Overview

It’s going to be a very bumpy, successful ride down your driveway. Why? Two words: Proline® fungicide. With its broad-spectrum leaf disease control and suppression of fusarium and gibberella ear rot, you can expect a lot more from your corn. Plus it’s the only fungicide on the market offering stalk rot suppression. Hey, higher yields and higher quality means deeper potholes. Sounds like a good problem.

In 2014, the Grain Corn Ear Mould and Vomitoxin Survey carried out by Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) to determine ear mould incidence and the occurrence of mycotoxins in the grain, showed that high DON concentrations (>5.0 PPM) was closely associated with ears that had Western Bean Cutworm (WBC) feeding.

Remember to scout for WBC as feeding damage fosters the development of ear moulds and toxin development. If damage is evident, apply Proline to protect the yield and quality of your corn crop.

Application Tips

Canola Protection



Research results show that Proline sets a new standard for disease control in canola. Proline provides a high level of consistent sclerotinia control when applied between the 20% and 50% flower stage.

Cereal Protection



Research has shown that Proline provides the best protection globally in both wheat and barley against fusarium head blight (FHB). Research has also shown that cereal crops treated with Proline can result in grain with significantly reduced levels of mycotoxins, especially deoxynivalenol (DON). When Proline is applied to wheat at early flowering, DON levels are dramatically reduced compared to an untreated check.

Corn Protection



Proline is the only fungicide registered to suppress fusarium and gibberella ear rot, and because of its activity on gibberella ear rot, Proline effectively reduces DON levels, too. Proline provides the best yield increase when disease is present – giving you a better return on your investment.

Features and Benefits:

  • Produces higher yields and better quality corn
  • The only fungicide registered to lower DON levels
  • The only fungicide registered for stalk rot suppression
  • 2 rate options: leaf disease rate and DON reduction rate (fusarium and gibberella ear rot suppression)
  • Controls more diseases than any other corn fungicide
  • Provides both post-infection and protective disease control
  • Brought to you by the fungicide experts at Bayer CropScience
  • Registered for aerial protection

Application Tips:

  • Fields should be scouted for early disease symptoms, particularly when susceptible varieties or hybrids are under prolonged conditions favourable for disease development
  • Optimal efficacy relies on thorough spray coverage. Ensure spray equipment is set up to maximize spray coverage and use flat fan nozzles
  • A non-ionic surfactant may be added at 0.125 %v/v
  • Rainfast in 2 hours

Timing
Wheat Timing of application is critical. For optimum protection against Fusarium head blight, apply from when at least 75% of the wheat heads on the main stem are fully emerged to when 50%of the heads on the main stem are in flower
Barley Unlike wheat, which flowers after it has completely headed, barley begins to flower in the boot. While the disease can infect the barley head prior to total head emergence, it is important to wait until most of the barley heads have emerged to attain maximum coverage. Applying Proline at this time will protect the exposed florets from the risk of infection. Delaying application past head emergence will reduce protection and increase the risk of disease infection
Canola The goal when applying Proline is to protect as many canola flower petals as possible, prior to significant petal drop. The optimum timing is between 20 and 30% bloom. Application with Proline fungicide can occuf from 20 - 50% bloom. To accurately identify the bloom stage of your crop, follow these steps: 1. Find the main stem. 2. Pull off the secondary branches. 3. Count only the open flowers on the main stem including aborted flowers and newly formed pods. 4. Sample several plants across the field.
Soybeans R 1-R 5 (R 2-R 3 or at onset of pod formation is optimal).

For all other crops consult the label.
