MIRAVIS PRIME® offers value in horticulture disease control
Miravis Prime is a newly registered fungicide offering protection against hard-to-control diseases in fruit and vegetable crops. It delivers the strength of two active ingredients for powerful and long-lasting control of sclerotinia, botrytis and powdery mildew in lettuce and leafy vegetables, berry crops, grapes and potatoes.
Complementary active ingredients fludioxonil (group 12) and pydiflumetofen (group 7) attack fungi at four different sites to offer optimum protection. Trials and commercial trial sites have shown this unique combination improves both the yield and quality of produce.
Miravis Prime is best used as a protectant fungicide, providing early defence against disease development. Fludioxonil, works as a protectant on the surface of the plant, while pydiflumetofen moves very quickly into the waxy cuticle giving long lasting protection. With contact, translaminar and some xylem movement, Miravis Prime offers ideal plant protection in both open field and protected cropping situations. The combination of two modes of action also helps mitigate the onset of resistance.
Lettuce and Leafy Vegetables
MIRAVIS PRIME is registered for control of Sclerotinia sclerotiorum, Sclerotinia minor and Botrytis cinerea in lettuce and leafy vegetables including spinach, kale and rocket.
“Trials and field demonstrations of MIRAVIS PRIME have shown outstanding control of sclerotinia, even in high disease pressure situations,” Syngenta Technical Services Lead, Dr Brandy Rawnsley said.

MIRAVIS PRIME featured at the 2020 East Gippsland Vegetable Innovation Days (EGVID), as well as the Syngenta GrowMore field demonstrations in the Adelaide Plains.
At one commercial site, there were 80 infected heads of lettuce in the growers’ standard program and only 33 in the Miravis Prime treated area (8 beds x 50m). “With current prices to growers at around $1- a head,the product delivers great return on investment ” Dr Rawnsley said.
“Throughout trials of MIRAVIS PRIME in lettuce, we observed fantastic control of sclerotinia, unlike anything else we’ve seen,” Dr Rawnsley said, “advisors who accompanied us were really confident with the results they saw”.
MIRAVIS PRIME is also registered for control of botrytis in all berry crops while also controlling powdery mildew in strawberries.
A one-day withholding period in berries allows use close to harvest; and a one-hour rain fastness offers growers flexibility of application ahead of rain or scheduled irrigation. With broad compatibility with other agricultural products, this suspension concentrate is easy to use within a protectant spray program. Trials have consistently showed that MIRAVIS PRIME increases marketable yield compared to industry standards (Figure 2).
“No one wants to see their hard work go to waste, particularly at harvest, making MIRAVIS PRIME an important new crop solution for the berry industry,” Dr Rawnsley said.

Botrytis protection as well as powdery mildew control
MIRAVIS PRIME also has registration for use in grapes for fresh and dried fruit production and wine grapes produced for the domestic market.
Thirty trials conducted in Australia and New Zealand all demonstrated MIRAVIS PRIME provided equivalent, and often superior, control of botrytis in grapes compared to SWITCH and also other registered fungicides Teldor, Scala and Custodia.
One trial, in South Australia, showed MIRAVIS PRIME delivered excellent control of botrytis under heavy disease pressure (Figure 3).

Easy solution for early blight
MIRAVIS PRIME offers growers a perfect solution to control sclerotinia in potatoes, while also providing excellent control of botrytis and early blight. “MIRAVIS PRIME gives excellent control of sclerotinia when there are limited options available” advised Dr Rawnsley. “It is a good fit in spray programs where sclerotinia poses a threat to potato production.”
"MIRAVIS PRIME is really going to add value to a growers spray program when targeting hard-to-control diseases, in high-value horticultural crops.”
