Frequent rainfall encourages water mould pathogens to become highly active, resulting in troublesome stem canker disease for growers. Valifenalate comes with its unique broad-spectrum fungicidal ability and rainfastness, allowing crops to receive long-lasting protection and continue resisting stem canker strongly.

In the vast orchards of durian plantations, growers always hope their durian trees can stand strong and remain lush and green. However, in Malaysia’s rainy conditions, water mould pathogens are relatively active, often bringing the headache of stem canker disease, also known as black patch disease. The outbreak of stem canker can cause durian leaves to turn yellow, branches to wither, and even seriously damage the tree, becoming a major threat to durian orchards.

High Penetration Builds a Protective Barrier

To address this type of disease, Advansia offers a dual-active-ingredient product, Valifenalate plus Mancozeb, which can effectively prevent diseases caused by downy mildew and water mould pathogens. With Valifenalate as the main active ingredient and Mancozeb as support, the combination of these two ingredients creates a synergistic effect, allowing Valifenalate to deliver better efficacy in suppressing water mould damage.

The spread of stem canker mainly depends on microscopic spores that cannot be seen by the naked eye. With the help of rainwater and wind, these spores continuously reproduce and invade the trunks, leaves, and fruit surfaces. Once they attack the tree, they release toxins, causing the bark to rot, leaves to turn yellow, fruits to dry up, and the overall health of the tree to decline rapidly.

Valifenalate carries a unique broad-spectrum fungicidal ability. It mainly works by destroying the structure of fungal cell walls, effectively eliminating fungi that invade the tree as well as fungal carrier spores. Whether they hide on the leaf surface, in bark cracks, or in the mud layer, they cannot escape its effect. With strong penetration, it spreads rapidly like water throughout the tree, forming a protective barrier and destroying pathogens at the budding stage.

In addition, pathogen spores often invade through wounds on the tree. When durian trees suffer wind damage, broken branches, fruit drop, or pruning wounds, these openings become the favourite “entrances” for pathogen spores. Valifenalate has a powerful wound-sealing effect. It can quickly cover the wound surface, forming an invisible protective film that blocks the pathogen’s invasion pathway and cuts off the entry of stem canker spores.

Providing Long-Lasting Protection for Crops

It is also worth mentioning that Valifenalate has long-lasting properties. After application, it can quickly fix onto the plant surface and penetrate into the inner layer of the bark. This forms rainfast protection, allowing crops to receive long-term protection. It is like activating a protective shield function for the tree, keeping durian tree wounds “dry, clean, and well protected”, while continuously suppressing pathogen reproduction and spread.

This product can be applied to different parts of fruit trees and different targets. For prevention on the upper plant parts, it is recommended to mix 20g with 20 litres of water and spray evenly on the leaf surface. For root protection, the recommended dosage is 100g mixed with 20 litres of water and drenched onto the tree head.

For infected areas on the tree body, it is recommended to first remove the rotten bark, then mix 50g with 1 litre of water and brush it onto the affected area. Due to the disease-prevention properties of Valifenalate, it can remain attached to the affected area for 5 to 7 days, helping protect the wound from secondary fungal invasion.
