Preventing Common Propagation Diseases

Preventing Common Propagation Diseases

Protecting plants during propagation can be a challenge. Unrooted cuttings and young seedlings generally require warm temperatures along with frequent misting or high humidity so they can root into the planting media. This warm, humid environment also provides optimal conditions for spores of pathogenic agents to germinate, invading wounds and tender plant tissue. Plants in propagation can be at risk of developing various diseases including foliar blights caused by Botrytis cinerea, leaf spots caused by Alternaria, Colletotrichum and Myrothecium spp. as well as lower stem rots. Young seedlings are also at risk of damping-off from Pythium, Phytophthora and Rhizoctonia spp. when the growing media is wet for a prolonged period of time.

Start strong. Stay protected.

Mural® fungicide is a broad-spectrum option for greenhouse and nursery growers to combat these destructive diseases during propagation. It is labeled to control more than 50 ornamental diseases, including Botrytis, leaf spots, rusts, powdery mildew, as well as many soil-borne diseases. Mural offers the flexibility to be used as a spray or a drench, providing effective disease protection in propagation and after transplant.

One of the two active ingredients in Mural, azoxystrobin, is in the Strobilurin class of chemistry, which also provides plant health benefits at low rates. Azoxystrobin is systemic and offers xylem mobile movement, meaning it is absorbed by the plant and translocated upward to protect new growth. Mural also contains Solatenol®, an advanced generation SDHI (succinate dehydrogenase inhibitor), which binds to the waxy layer of plants and slowly penetrates into the tissue, creating a barrier of protection. Mural inhibits spore germination and mycelial growth, providing plant protection on the inside and out.

Enhanced root growth + disease control ​​​​​​​

The following photos show the enhanced root growth that Mural and Heritage® fungicides provide. Treatments were applied as a spray to poinsettia cuttings four days after sticking. Plant height and root growth were evaluated 23 days later. It is important to note that these rates of Mural and Heritage provide excellent disease protection – the primary reason for using a fungicide – with the added benefit of enhanced root development.

Improved root development is also observed when Mural is applied as a drench to protect crops from root and stem diseases.

Prevent disease from propagation to finish

With its broad-spectrum disease control and root health benefits, including increased root density, Mural is an ideal fungicide for use in propagation as a spray or as a drench after transplanting. Its many use sites make it a versatile option for any grower.
