How to Control Fall Armyworm in Maize in 5 Ways

Fall armyworm is an insert which cause excessive damage to maize and other evergreen plants. In maize, it cause damage almost in all stages of its growth, to the point of causing damage to corn ear. When the maize plant is at an early stage, it cause damage by eating the maize plant leaves, and this leaf feeding cause more damage as these leaves are used for photosynthesis which accelerates its growth. Fall armyworm also cause direct damage to corn ear, making it uneconomical.

In summary fall armyworm can be controlled by using; Chemical, biological, cultural, natural and Integrated pest management (IPM) control methods, which is a combination of biological and chemical control. This article will provide in detail on how you can control fall armyworms through these 5 methods.


5 Ways to Control Fall Armyworm

The following are considered 4 ways for controlling fall armyworm.

1. Chemical control

Chemical method to control fall armyworm involves using pesticides, fungicides and bactericides to put down the fall armyworm population. With this method, you apply chlorpyrifos, sulprofos, and thiodicarb, which kills fall armyworm and these are new chemicals to some individuals, but they have been proven to show positive results. Fall armyworm larvae, can be chemically controlled using synthetic pyrethroids. Sometimes pyrethroids are used in combination with chlorpyrifos.

The disadvantage of using chemical method to control fall armyworm is that, it kills other beneficial inserts, and could cause poisoning damage to human and plants, when applied to vegetable leaves.

2. Biological control of fall armyworms

Biological method of controlling fall armyworm involves using living organisms to suppress fall armyworm population, making it less damaging than it would otherwise be. There are three primary methods available for biological control of fall armyworm and these are; Mass rearing and periodic release, conservation of existing natural enemies and introducing new natural enemies and establishing a permanent population.

In our case, fall armyworms can be effectively controlled by mass rearing of introduced parasitoids which is done in African laboratories, and later released in the field to increase parasitism.

3. Cultural control of fall armyworms

Cultural method to control fall armyworm refers to the manipulation of the crop production system or cultural practices to reduce or eliminate fall armyworm population. The basis of cultural control is to make the crop environment unfavourable to fall armyworm. It is mostly used as a preventative measure of fall armyworm.

In our case, cultural method to control fall armyworm in maize will involve using intercropping, weeding, planting high resistant varieties, among others. The control techniques avoid or minimize the fall armyworm impact on the maize crop.

4. Natural control of fall armyworm

Natural control of fall armyworm refers to the maintenance of insect populations within certain bounds by environmental factors, or conditions. Both non-biological and biological factors contribute to the fall armyworm natural control.

Natural control include physical factors such as weather e.g. cold winters can reduce some fall armyworm populations naturally. This method, relies on chemical free ways. In our case you could apply a mix of ash and sand to put down the fall armyworm population.

5. Integrated Pest Management (IPM) of fall armyworm

Integrated Pest Management (IPM) of fall armyworm involves using a combination of techniques such as biological control methods, cultural method, habitat manipulation, and use of resistant varieties. It is an ecosystem-based strategy which focuses much on long-term prevention of fall armyworm or their damage through a combination of the above techniques.


In conclusion, this article has uncovered 5 ways which can be used to control fall armyworm, which cause excessive damage to maize plant. Among others, the article has uncovered that, chemical, biological, natural and cultural control, are some of the methods which can be used to control fall armyworm in maize plants.
