Protectant Vs Eradicant Fungicide: Which one to use for your crops?
Fungal diseases can cause significant damage to crops, resulting in yield loss and lower quality produce. To prevent these diseases from taking hold, farmers have two options: protectant and eradicant fungicides. Both types of fungicides are designed to control fungal diseases, but they work in different ways. In this article, we'll explore the differences between protectant and eradicant fungicides, so you can make an informed decision about which one to use for your crops.
What are protectant fungicides?
Protectant fungicides, as their name suggests, are designed to protect crops from fungal diseases. These fungicides are applied before any signs of disease appear and create a barrier on the surface of the plant that prevents fungi from penetrating and infecting it. They work by creating a physical or chemical barrier that prevents the fungus from entering the plant tissue. Some examples of protectant fungicides include copper oxychloride and sulfur.
The main advantage of using protectant fungicides is that they offer long-lasting protection against fungal diseases. Since they are applied preventatively, they can remain effective for several weeks. Protectant fungicides are also less likely to cause resistance in fungi since they do not target specific genes or pathways.
However, there are some downsides to using protectant fungicides. For one, they must be applied before any signs of disease appear, which means farmers need to be proactive in monitoring their crops for potential fungal infections. Additionally, protectant fungicides may not be effective against all types of fungal diseases, particularly those that penetrate the plant tissue before symptoms appear.
What are eradicant fungicides?
Eradicant fungicides, on the other hand, are designed to eliminate fungal infections that have already taken hold. These fungicides are applied after the onset of disease symptoms and work by killing the fungi directly. Eradicant fungicides are systemic, meaning they penetrate the plant tissue and attack the fungus at its source. Some examples of eradicant fungicides include azoxystrobin and pyraclostrobin.
One of the benefits of using eradicant fungicides is that they can quickly bring a fungal infection under control. They are particularly effective against fast-spreading diseases that can quickly take over a crop if left unchecked. Eradicant fungicides are also more flexible than protectant fungicides since they can be applied when needed rather than preventatively.
However, there are also some drawbacks to using eradicant fungicides. They can be more expensive than protectant fungicides and may require multiple applications to completely eliminate the fungus. Additionally, eradicant fungicides are more likely to cause resistance in fungi since they target specific genes or pathways.
Which one to use for your crops?
When it comes to choosing between protectant and eradicant fungicides, there is no one-size-fits-all answer. The best option for your crops will depend on a variety of factors, including the type of crop, the stage of growth, and the likelihood of fungal infections. In general, protectant fungicides are a good choice for crops that are prone to fungal infections, while eradicant fungicides are better suited for crops that have already been infected.
It's also important to consider the potential risks and benefits of each type of fungicide. Protectant fungicides offer long-lasting protection and are less likely to cause resistance, but they require proactive monitoring and may not be effective against all types of fungal infections. Eradicant fungicides can quickly bring a fungal infection under control, but they are more expensive and may cause resistance in fungi.
In conclusion, both protectant and eradicant fungicides have their strengths and weaknesses. The key to choosing the right fungicide for your crops is understanding the differences between them and weighing the benefits and risks. By doing so, you can ensure that your crops stay healthy and free from fungal infections.
