Boscalid 50% Wg/Wdg 98%Tc Fungicide

Features of Boscalid

As a new generation fungicide, Boscalid has distinct characteristics compared to traditional fungicides, primarily reflecting in three aspects:

1. Target Specificity
Unlike broad-spectrum fungicides such as triazoles and methoxyacrylate fungicides, Boscalid is also broad-spectrum but is only effective against diseases that exhibit mold or rot symptoms, such as gray mold, powdery mildew, sclerotinia disease, root rot, or other decay-related diseases. Particularly against gray mold in crops, when mixed with fludioxonil, it can eliminate gray mold pathogens within hours.

2. Ascending Conductivity
Boscalid features a unique ascending conductivity, making it suitable for not only leaf spraying but also root drenching or seed mixing. Although Boscalid does not possess systemic internal conduction, it can transmit within the leaf through its permeation function upon contact with the leaf surface, and this permeation occurs rapidly. If it rains within an hour after application, re-spraying is unnecessary.

While Boscalid lacks internal systemic conduction, it has the ability to transfer through the root system to the top of the plant. Therefore, when used for root drenching or seed mixing, it can effectively prevent root diseases and also provide protection against foliar diseases (such as gray mold, powdery mildew, and early blight).

3. Prevention + Treatment
Boscalid offers long-term protection for crops against pathogen invasion. For example, regarding gray mold, Boscalid demonstrates a strong inhibitory effect on the germination of pathogen spores, effectively preventing the elongation of germ tubes and the formation of attachment organs, which highlights its good preventive action. It also suppresses the hyphal growth and spore formation of gray mold pathogens, thereby reducing the opportunities for secondary infections. This results in a single application providing long-lasting protection.

Research data obtained from experimental departments indicate that after spraying Boscalid, the efficacy can last for about 15 days on strawberries. This duration of effectiveness is difficult to achieve with other similar fungicides.
