Pyraclostrobin fungicide is a mitochondrial respiration inhibitor. It blocks electron transfer between cytochrome b and C1. This inhibition prevents ATP production. Consequently, it leads to cell death. Pyraclostrobin strongly suppresses spore germination in pathogens. It shows significant antibacterial activity against various fungal pathogens. It has protective and curative effects. Pyraclostrobin fungicide penetrates well and can be applied via foliar sprays, surface treatments, or seed treatments. It is highly selective and safe for crops, humans, livestock, and beneficial organisms. It causes minimal environmental pollution. Additionally, it enhances physiological functions in crops and boosts their resilience.
Boscalid is a succinate dehydrogenase inhibitor. It inhibits fungal respiration. After application, the solution penetrates the leaves. The plant absorbs the solution. It distributes to the leaf tips and margins. Boscalid interacts with the mitochondria of pathogenic fungi. It binds to protein complex I in the electron transport chain. This obstructs the tricarboxylic acid (TCA) cycle. ATP synthesis in plant pathogenic fungi is disrupted. This interference affects cell division and growth, leading to fungal death. Therefore, Boscalid effectively prevents plant fungal diseases.
Boscalid has dual activity. Complex II plays a key role in fungal metabolism. It transfers energy to form high-energy electrons during fungal respiration. It also helps transport components of the TCA cycle. This blocks amino acids and lipids, creating an important crossover. Diniconazole inhibits protein complex II to disrupt fungal energy production. Consequently, it suppresses fungal growth.
Features of Pyraclostrobin
1. Broad Spectrum of Activity and Wide Application Range
Pyraclostrobin fungicide exhibits excellent activity against nearly all types of fungal diseases. It can be used to control leaf spot diseases, rust, powdery mildew, downy mildew, blight, anthracnose, scab, brown spot, damping-off, and other plant diseases caused by various fungal pathogens. It is widely applicable to over 100 crops, including wheat, peanuts, rice, vegetables, fruit trees, tobacco, tea plants, and ornamental plants.
2. Combination of Prevention and Treatment with Health Benefits
Pyraclostrobin fungicide has both protective and curative effects, with good penetration and systemic action. It can be applied through foliar sprays, surface treatments, and seed treatments.
Additionally, Pyraclostrobin fungicide can induce physiological changes in many crops (especially cereals), enhancing nitrogen absorption during rapid growth stages, reducing ethylene biosynthesis, and delaying crop senescence. When crops are attacked by pathogens, it accelerates the formation of resistance proteins, improving the crops' innate immunity and enhancing their resilience to adverse growth factors.
3. Good Compatibility, Safe and Low Toxicity
Pyraclostrobin fungicide can be mixed with various fungicides, such as benzimidazole, mancozeb, acibenzolar-S-methyl, and triazoles. This not only broadens its spectrum of activity but also allows for synergistic effects. It can also be mixed with various insecticides, plant growth regulators, and foliar fertilizers, achieving multiple functions in a single application, including disease prevention and treatment, pest control, growth regulation, and nutritional supplementation. This versatility is a key reason why Pyraclostrobin fungicide frequently appears in various yield-increasing formulations.
Moreover, Pyraclostrobin fungicide is characterized by its resistance to rain wash-off, long-lasting efficacy, low toxicity, and safety for users and the environment.
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.
Application of Pyraclostrobin
Pyraclostrobin fungicide can be used on various crops, including wheat, peanuts, rice, vegetables, fruit trees, tobacco, tea plants, ornamental plants, and lawns. When pathogens come into contact with the fungicide, it inhibits their mitochondrial respiration and spore germination, ultimately leading to cell death and significantly reducing the spread of the disease.
Pyraclostrobin effectively controls multiple diseases such as powdery mildew, fusarium head blight, downy mildew, brown blight, leaf spot, scab, black rot, anthracnose, wilt, and root rot. At the early stages of disease onset, we can apply a 2000-fold dilution of 25% pyrazole fungicide via foliar spray, repeating every 7 days for 2 to 3 applications based on disease severity.
Prevention should be the primary focus; spraying before or at the early stages of disease can help minimize losses. If crops are already in the late stages of disease, we can mix it with other fungicides to enhance the control effect.
