Jul 12, 2017Protect at row closure with Endura® and Priaxor® fungicides
{Sponsored} At row closure, your crop is vulnerable to various diseases, including white mold and early blight, which can affect yields. Endura® and Priaxor® fungicides from BASF can be used to tackle these diseases. Add these fungicides to your toolkit to better protect your crop before and after row closure.
Endura fungicide is a market standard for controlling white mold and is also effective against early blight in areas where Fungicide Resistance Action Committee (FRAC) Group 7 resistance has not been selected. “These are the main two diseases that we’re targeting around that row closure stage,” said BASF technical service representative Tye Shauck.
“We recommend the application to be made just prior to row closure, because Endura fungicide, like most fungicides, works best when applied preventively,” he said. “White mold spores will infect senescing flower petals, and then grow into the stem and leaf tissues. It is important to target row closure because it is generally around the time of flowering.”
Early blight infections will also occur at this time during the growing season.
“Applying just prior to row closure will also offer better protection due to better spray coverage in the lower canopy,” said Shauck. “If you wait until total row closure, it’s harder to get the fungicide to the lower plant canopy for complete protection.”
Priaxor fungicide, the most recent fungicide for potatoes from BASF, is most effective at controlling other diseases at different times in the growing season. For example, black dot at early rosette or Rhizoctonia if applied in-furrow at planting, said Shauck. However, around the time of row closure, Priaxor can be used to control early blight in areas without FRAC Group 7 resistance and will also promote plant health.
Priaxor fungicide contains two active ingredients: F500 is a FRAC Group 11 active ingredient also found in Headline® fungicide and Xemium® fungicide which a new FRAC Group 7 active ingredient. F500 helps Priaxor provide plant health benefits in addition to disease control.
“That active ingredient will help the plant more efficiently assimilate nitrogen,” said Shauck. “It will also help the plant to mitigate stresses in the summer months, such as heat stress, which can make potato plants more susceptible to diseases like white mold and early blight.”
Endura and Priaxor fungicides may be used together in a disease management program.
“However, both of these fungicides have a FRAC Group 7 active ingredient, so for resistance management, we recommend no more than two sequential applications of the same mode of action.”
