In recent years, the control of tomato gray mold has increasingly relied on chemical methods. However, the gray mold pathogen has gradually developed resistance to commonly used **pesticides** such as thiophanate-methyl and procymidone. This has raised concerns about the long-term effectiveness of these traditional fungicides. In response, researchers have turned their attention to new compounds like pyridine azole, which shows promising results in both prevention and treatment.
Pyridine azole exhibits strong systemic activity and can effectively inhibit key stages of the gray mold pathogen, including mycelial growth, spore germination, and germ tube elongation. Importantly, its mode of action differs from that of thiophanate-methyl and procymidone, meaning there is no cross-resistance between these compounds. This makes it a valuable alternative for managing resistant strains.
In 2009, Wujiang City’s agricultural department conducted a field trial using 25% pyridine emulsifiable concentrate (EC) to manage tomato gray mold. The test was carried out in a greenhouse setting, with three different concentrations of the product: 750 times dilution, 1000 times dilution, and 1500 times dilution. For comparison, 50% procymidone wettable powder and 70% thiophanate-methyl wettable powder were also tested at a 1000 times dilution. Each application involved spraying 60 kg of solution per acre, with treatments applied every 7 days—three times in 2009 and four times in 2010.
The results were impressive. The 25% pyridine EC at 750 times dilution showed the highest efficacy, achieving a two-year average control rate of 94.7% and 94.4%. At 1000 times dilution, the control rate was slightly lower but still significantly better than the conventional fungicides, with 89.5% and 87.5% over two years. In contrast, the 50% procymidone WP and 70% thiophanate-methyl WP achieved only 79.7%, 82.1%, and 69.5%, 70.2%, respectively. Even the 1500 times dilution of pyridine EC performed well, with an average control rate of 83.3% and 78.5%.
Based on these findings, 25% pyridine EC was found to be more effective than the standard fungicides currently in use. As a result, **pesticide manufacturers** recommend applying it at a concentration of 750–1000 times dilution (approximately 60–100 ml per acre). When disease pressure is high, the dosage can be increased accordingly. It is best to apply the product early in the infection cycle and repeat the treatment every 7 days for 3–4 consecutive applications.
To prevent the development of resistance, it is advisable to use pyridine EC in combination with other fungicides. This approach not only enhances efficacy but also prolongs the lifespan of the active ingredient. With proper usage, pyridine azole offers a sustainable and effective solution for managing tomato gray mold.
Aerial Drop Hardware
Aerial drop hardware refers to the equipment and components used in the installation and deployment of aerial drops in telecommunication networks.
An aerial drop is a physical connection between a utility pole or other support structure and a customer's premises, typically used to provide services like telephone, internet, or cable TV. The aerial drop hardware includes various components such as:
Stainless Steel Band: The band that carries the signals from the main distribution network to the customer's premises. It is usually a coaxial cable or fiber optic cable.
Drop Wire Clamp: Drop Wire Clamp is used to support one and two pair telephone or fiber drop wire at span clamps, drive hooks, house hooks and various drop attachments. Made from 3 pieces stainsteel removable construction, Dimpled, Serrated and Plastic shim are available.
Anchoring hardware: Hardware used to secure the aerial cable and drop wire to the support structure, such as clamps, brackets, or hooks.
Suspension hardware: Hardware used to support the weight of the aerial cable and maintain its proper tension, such as suspension clamps or brackets.
Splitters, connectors, and terminations: Components used to split or combine signals, connect different sections of cable, or terminate the cable at the customer's premises.
Cable Lashing Clamp used for securing lashing wire at end of span.
Acetal Strap Cable Ties made by toughened weather acetal. Temperature Range:
-40℃ to 85℃. Black colour, general packing in 50 feet length, can cut the strap at different length in practice. The Double Locking Heads and Tool are available.
YokeLink Stainless steel Banding have high acid resistance, corrosion resistance and tensile strength, easy and convenient operation.
These hardware components are designed to provide a secure and reliable connection for the transmission of signals between the service provider's network and the customer's premises.
