Proline

Overview

Proline® is a new-generation fungicide providing broad-spectrum disease control in a variety of crops. Proline contains the active ingredient prothioconazole and belongs to a new sub-class of azole chemistry called the triazolinthiones. A proven performer in cereals and canola, Proline is now taking on some of the toughest diseases corn growers can face. Unlike its competitors that are strobilurin-only fungicides, Proline safeguards the yield and quality of corn by offering both curative and protective properties that can be applied at the first sign of disease symptoms.

Additionally, 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.

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.

Corn Protection

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.
Corn Apply from the development stage of corn between the tip of stigmata visible (silking, BBCH 63) to the stigmata drying stage (silk browning, BBCH 67) to reduce both disease symptoms and levels of mycotoxin in the grain.
Soybeans R 1-R 5 (R 2-R 3 or at onset of pod formation is optimal).

For all other crops consult the label.
