Proline Corn

Overview

Like any good grower, you know when you’ve got a job to do, you better do it right. So, it only makes sense that growers everywhere are trusting Proline to lower DON levels, control late season leaf diseases and maximize their corn yield. Go for gold with Proline.

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 toxins. If damage is evident applying an insecticide at early silking and tank-mixing it with Proline will protect your crop from late season leaf diseases, lower DON levels and maximize your crop’s yield.

Application Tips

Corn Protection



Proline is the only fungicide registered to suppress fusarium & gibberella ear rot and stalk rot pathogens. Because of its activity on ear rot, Proline effectively reduces DON levels. All this plus late season disease control means higher yields at harvest.


Proline Maximizes Your Corn Yield And Provides Best-In-Class Late Season Lead Disease Protection And DON Reduction



Comparison of disease severity, DON suppression, and yield using Proline fungicide compared to competitors
Apply Proline fungicide at Early R1 Day 0 growth stage to optimize control of leaf diseases and DON reduction
Growth Stage   Early Tassel
first signs of tassel are visible
  VT DAY -2
begins when last branch of tassel is completely visible
  Early R1 Day 0
begins when first silk is visible outside husk

scout for this
  Full R1 Day +2
lots of moist silk is visible outside husk
R2 Day +10
silks are darkening and drying out
R3
silks are brown and dry or becoming dry

Apply from the development stage of corn between silking and silk browning. Scout for Day 0 (early R1) when the first silks are present out the husk.

 

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.

Rate
A non-ionic surfactant is not required when applying Proline on canola, pulses, corn or soybeans.
Canola 128 mL/ac. 5.1 L jug (standard rate) treats 40 acres
Cereals 128 mL/ac. 5.1 L jug treats 40 acres (apply with non-ionic surfactant)

  • Fusarium and gibberella ear rot suppression (DON reduction) and late season leaf disease control: 420 mL/ha (170 mL/ac.) Each 5.1 L jug treats 12 ha (30 ac.)
Soybeans 128 mL/ac. 5.1 L jug treats 40 acres
Water Volume
Aerial - 50 L/ha (4.5 gal./ac.)
