Our Comprehensive Buying Guide

 

Fungi infections are one of the biggest threats your farm yield could face. These microbial diseases can cause severe damage, leading to massive crop loss. Statistically, these infections cause approximately 75% of plants’ microbial diseases. If you don’t take immediate action, these diseases can spread throughout your garden. To prevent this, you need to apply specific treatments. Here is our comprehensive guide to buying the best product.

Analyze the plant’s symptoms

One of the first things you should be looking for before you decide to purchase any plant fungicide is the signs of the disease. Plants can be affected by numerous diseases, and some of them are not caused by fungi, but by insects.

The latter usually leave holes in the leaves, while fungi diseases that are often treated with a copper product are usually signaled by spots on the leaves. To know what the best fungicide for your plants is, you must first understand what caused the disease.

 

Consider the product’s composition

This is another key criterion to take into account when purchasing these products. Even the most affordable fungicides should have the composition clearly stated on their label. Moreover, for many products, you can find a review or description online, and there, the chemical composition is often detailed.

This will allow you to see what chemical you are about to apply and, in case the disease is not very severe, to opt for solutions that are milder and don’t contain a high concentration of chemicals.

 

Choose the application method

There are different methods of applying these solutions. You can get a liquid copper fungicide, for example, or other types of fungicides that come in liquid form and are quite easy to use. Once you apply this type of copper fungicide, it sticks to the plant’s surface.

Another option you might find practical are solid fungicides that are sold as powders or granules. They are normally applied to the soil and cause different amounts of dust.

Getting a fungicide spray is another practical and time-effective solution as these products are easy to apply and usually bring fast results.

Contact or systemic?

In terms of their action, there are two main categories of fungicides: contact and systemic. Contact fungicides kill the disease when they come into contact with the fungi and prevent them from further invading the plant’s tissues.

These fungicides are meant to kill the pathogen from the first contact, and for this purpose, they are considered some of the best products. Nonetheless, they have a reduced mode of action.

Systemic fungicides, on the other hand, are first absorbed into the plant’s tissue and then start acting, usually providing lasting results.

The best moment to apply these fungicides is when the plant is in the growth process. This will allow the substance to easily circulate throughout the plant. These products are efficient even after the disease has started spreading in the plant’s tissue.

 

Get the best value for your money 

You can buy a cheap fungicide and still benefit from some degree of efficiency in tackling the disease. There are cheap fungicides that offer good results, but you should be wary of extremely low prices, especially if the product is not accompanied by a comprehensive set of instructions.

To make sure you are getting the best value for your money, it’s always a good idea to read the best fungicides reviews you can easily find online and see how the products worked in different circumstances.

 

 

Frequently Asked Questions:

 

Q: What kind of fungicide to use on the lawn for brown patch?

If you want to protect and treat your lawn, you need to use a specific fungicide for lawn. Brown patch is one of the common diseases that often affect the grass. The good news is that if you intervene in a timely manner by using a grass fungicide, you can minimize the damage and protect your beautiful green grass.

Brown patch is a fungal disease that manifests itself in warm and wet weather conditions. It can cause significant damage if you don’t treat it as soon as the first symptoms start to show. The main signs that you are dealing with brown patch are circular areas of withered grass.

You can tackle the problems caused by brown patch even with an affordable fungicide you can find in any store. However, the best lawn fungicide for this disease is typically a Daconil fungicide or a similar product from another well-known brand. This product contains Chlorothalonil, a strong active ingredient that kills this fungus by contact.

Q: What is a fungicide?

A fungicide is a type of pesticide that aims to treat plant diseases caused by fungi, hence their name. Fungi are the biggest crop enemy, causing the largest amounts of loss worldwide. To avoid the severe damage fungi can bring, you should find and apply a quality fungicide for your plants. If you read the best fungicides review above, you already have some reliable options.

These products can contain different types of ingredients and one of the most common options is to use a copper based fungicide. This natural ingredient is highly effective in killing different types of fungi. With copper fungicide concentrate, you can deal with diseases such as downy mildew, blight, powdery mildew, rusts, septoria leaf spot, or fireblight.

Fungicides can be applied differently based on their composition and form. There are liquid fungicides or solid ones that come as powder or granules. The liquid ones can be applied manually after preparing the solution from the concentrate or as sprays.

Moreover, there are specific products based on the plant’s type. You can get a fungicide for trees or grass or different types of crops.

 

Q: When to apply fungicide on lawns?

If your lawn starts showing signs of disease such as brown patchy grass, you should wait no longer and apply a lawn fungicide before the disease starts spreading. The damage that the fungus already produced cannot be reversed, not even with top fungicides.

For this reason, it is important to act promptly, as soon as you start noticing the first symptoms. The most obvious and common sign that shows your lawn is not feeling well are patches of brown or yellow grass. These areas are sometimes circular and they gradually extend as the fungi spread.

Other signs include areas of darkened or grey grass that often seem wet. The grass blades can also indicate the presence of fungi if they have dark, red, grey, or orange spots or if they become discolored.

Apply the fungicides as per their instructions, as soon as needed. Should you water lawn after applying fungicide? This is another essential aspect you should consider. If you apply contact fungicides, avoid watering the lawn afterward as the product will wash off.
