The best Organic Pesticides for vegetable’s diseases

Organic pesticides are usually considered as those pesticides that come from natural sources.

These natural sources are usually plants, minerals, fungus and bacterias.

Even if a product is considered to be organic, it is still a pesticide.

It is important to be careful when using any pesticide, even organic or natural pesticides.

Just because a product is thought to be organic, or natural, does not mean that it is not toxic.

Some organic pesticides are as toxic, or even more toxic, than many synthetic chemical pesticides.

Organic pesticides are different from conventional pesticides in terms of the materials used during pesticide


While “traditional” pesticides are based on sprays and preparations with high concentrations of toxins, organic

pesticides use substances that have lower concentrations of toxins, and therefore break down faster, and

accordingly, their damage to the environment, animals and humans is lower when working with organic sprays.

Organic spraying is not a completely natural spraying, as many people mistakenly think.

Although it is an environmentally friendly pesticide, more than the conventional pesticide, it is based on

substances that in the process of synthesis have become toxic chemicals, such as pyrethroids, which are a group of

pesticides extracted from sources found in nature in their raw form.

These are the pesticides that are allowed to be used in large scale, organic cultivations, and that organic farmers alowed to use:

Pay attention that these are not homemade pesticides, that some claim to work,

but real professional ones, that are selling and proven to work, on regular basis.

Note that organic pesticides are sometimes less efficient than the regular synthetic ones.
