WHAT ARE HERBICIDES USED FOR?

Herbicides are agents, usually chemical, used for killing or inhibiting the growth of unwanted plants, such as residential or agricultural weeds and invasive species. A great advantage of chemical herbicides over mechanical weed control is the ease of application, which often saves on the cost of labour. Most herbicides are considered nontoxic to animals and humans, but they can cause substantial mortality of nontarget plants and the insects that depend on them, especially when applied aerially.

WHAT ARE FUNGICIDES USED FOR?

Fungicides are pesticides that kill or prevent the growth of fungi and their spores. They can be used to control fungi that damage plants, including rusts, mildews and blights. They might also be used to control mold and mildew in other settings. Fungicides work in a variety of ways, but most of them damage fungal cell membranes or interfere with energy production within fungal cells.

Things to keep in mind when using Fungicides: 

• A fungal disease in plants can be misdiagnosed easily. Check with your local crop consultant for help identifying plant disease. They may also be able to recommend a treatment strategy.
• Often, plant diseases are transmitted when leaves are wet. Ground level watering and good air circulation can be used to keep leaves dry.
• Many fungicides remain on the surface of plant tissues and do not spread throughout the plant. Others penetrate the cuticle and circulate through plant tissues.
• Although they can slow or stop the development of new symptoms, many fungicides are designed only to prevent disease. These are not highly effective after symptoms have developed.

WHAT ARE Insecticides USED FOR?

Insecticides are pesticides that are formulated to kill, harm, repel or control one or more species of insect. Insecticides work in different ways. They come in different forms including sprays, dusts, gels, and baits. Contact T&S Crop Service to find out which insecticide is right for you and your crops.
