Organic Solutions for Managing Cutworm Damage in Vegetables


Cutworms in gardens are a major menace to all the vegetables in Europe and more so for the farmers who refrain from using chemicals to defend their produce. This particular story tells the real life experience of a Dutch man who is experienced in growing organic crops; he is a farmer who cultivated vegetables one year and had a big problem of cutworm stains on most of the vegetables. We will describe how he tracks and controls the pest with organic treatment for cutworms and the possibility of sustainable solutions he implemented, the former being Novobac’s Met-Zone Granular Insecticide (organic treatment for cutworms​) and the latter the Metarhizium anisopliae bioinsecticide to reduce cutworm damage. Doing cutworm identification is the very necessary first step.

Cutworms causing harm to vegetable plants

A farmer from the Netherlands recounting of cutworm damage

An organic farmer in the Netherlands found vegetable stems neatly cut by suspected cutworm activity in his fields. Observing weak plants and devastated rows, he carefully examined the damage, suspecting cutworms had invaded his crops. Consulting agricultural specialists confirmed his cutworm diagnosis, and he sought effective control measures for the infestation.

Determined to avoid synthetic solutions, he chose an Integrated Pest Management approach to tackle the cutworm problem organically. He incorporated Novobac’s Met-Zone Granular Insecticide and Metarhizium anisopliae, ensuring effective biocontrol against cutworms without violating organic farming principles.

What are Cutworms and How to do Cutworm Identification

Appearance and Lifecycle

Cutworms are in fact caterpillars – the young of several types of night-flying moths. They come out in shades of brown to grey and are usually seen coiled in the ground in the course of the day. The cutworms are most prevalent during spring and early summer and survive in a humid condition that makes the two periods very risky for crops. Cutworm lifecycle is a very necessary part of understanding how to attack this pest.

  • Eggs: Burrowed in the ground, most commonly around the plants.
  • Larvae: Water during the evening and trim young plants close to the ground.
  • Pupae and Adults: The cutworm life cycle is such that after hatching, the larvae move to the surface of the ground to feed and then burrow in the ground to transform into pupate and finally there emerge the adult worms who start feeding and lay eggs to continue the cycle.

Damage Symptoms

  • Cutworms target young seedlings, cutting their stems at the base, causing them to lay flat on the ground.
  • They attack stems and lower leaves, leading to plant wilting and sometimes even causing plant death.
  • You might notice soil movement near cut plants where larvae have fed or moved around actively.

Infestation of cutworms in vegetable garden

Cutworm damage and its economic effect on farmers in Europe

In most parts of Europe, but especially the Netherlands, France, and Italy, cutworms are a menace to vegetable growers. There is a problem because the pest quickly destroys young crops, which results in financial losses for farmers who use only organic methods. By means of the cutworms, whole fields could be destroyed intact in certain regions, thus hitting the food chain in certain areas, and the income of farming communities. It’s most critical with organic farmers since they cannot use synthetic chemicals to deal with cutworms; therefore, biocontrol measures apply.

Managing Cutworms with Sustainable Solutions: A Dutch Farmer’s Approach for Organic Treatment for Cutworms

  1. Soil treatment and what was known as the physical barriers

The farmer carefully tilled the soil to reduce cutworm pressure, eradicating weeds and residues that attract moth eggs. He placed collars on young seedlings, acting as buffers to prevent the stems from being excised effectively.

  1. Light Trapping and Handpicking

The farmer used light traps to target and eliminate adult moths, reducing their egg-laying on the soil. By mimicking larvae foraging, he inspected soil around damaged plants in morning and evening to hand-pick them. His efforts aimed to minimize larval populations, enhancing overall pest management and protecting crop health efficiently.

  1. Biocontrol using Novobac’s Met-Zone Granular Insecticide for Cutworm damage control

Met zone treatment for managing cutworm damage

To achieve effective pest control, which was sustainable, the farmer included a Novobac Met-Zone Granular Insecticide in his control program. Their product, which is developed for the soil-inhabiting pests such as cutworms, offered concentrated efficacy due to the slow-release formulation that remained effective in the soil.

How Met-Zone Granular Insecticide Works

Met-Zone employs microbial action wherein active ingredients affect cutworm larvae upon ground contact, reducing their destructive potential immediately. Upon contact with larvae, the granules interfere with feeding mechanisms, preventing further damage to your plants effectively.

Application Method

  • Placement: Used generally around the plants especially where the cutworms are most dominant.
  • Timing: Used immediately after transplanting of seedlings and at mid season for consistent control of the pest.
  • Environmental Impact: Innocuous to helpful insects and could easily blend well with the usage of organic farming techniques.
  1. Biological Control using fungi Metarhizium anisopliae

Metarhizium anisopliae is another biologically derived fungicide that is an organic pesticide for cutworms, which shunt the farmer to fight cutworms which are soil inhabiting pests. This enzymatic fungus parasitizes on the larvae and, after a while, it does the killing by breaking the pest’s body away.

The biological probable summarized is ascertain as follows: How Metarhizium anisopliae Works

When applied to the soil, Metarhizium spores make physical contact with cutworm larvae and since then the spores germinate and invade the cuticular layer of the exoskeleton. This fungus eradicates larvae without affecting plants, beneficial insects or the environment and is ideal for use in an organic farm.

Thanks to the good observation of aspects of sustainability and biocontrol methods, the farmer succeeded to realize good production of vegetables even without huge losses from cutworms. The novel control technology was Metarhizium anisopliae when combined with Novobac’s Met-Zone Granular Insecticide; the crops were safe while the soil and other beneficial insects remained intact.

The largest innovation was to combine organic treatment for cutworms with fungi-based biopests. With my crops growing and yielding very well I knew that what I employed was sustainable and in accord with the works of nature.

What he was able to prove was that with proper strategy and with the right equipment and inputs, producers of organic crops can control cutworm infestation, while at the same time maintaining an organic farming approach understanding how to protect against cutworms sustainably.

Conclusion: The Odd World of Pharmacogenomics in Cutworm’s Organic Agriculture

Soil preparation, monitoring, and biocontrol are crucial components for managing cutworm damage effectively on your farm. Organic farmers can utilize Novobac’s Met-Zone Granular Insecticide and Metarhizium anisopliae for effective cutworm reduction. Incorporating these solutions helps farmers prevent crop attacks while boosting overall garden productivity and health.

Enhance your cutworm control strategies with these environmentally-friendly methods for combating vegetable garden pests. Farmers should understand cutworm identification to effectively apply organic treatments and manage farm attacks efficiently.
