Why choosing biological control methods for armyworms in corn and wheat
Armyworms in corn and wheat farms are the biggest problem for farmers around the world. These pests, which are widely known for their fast feeding and their large colonies, can destroy the fields in a matter of days if they are not controlled properly. The usual chemical insecticides were the choice of the traditional farmers, but, today, the transition to sustainable farming has shown the advantages of the biological control methods. Of course, there are many pesticides on the market but Bt is the one that is really effective.
Understanding Armyworms
Armyworms are the worms of the larvae of the moths that belong to the family Noctuidae. The most frequently talked about species that is related to agriculture is the fall armyworm (Spodoptera frugiperda) which specifically feeds on crops like corn and wheat. These animals are called this way because of their ability to move over the fields in big numbers, and they consume almost all the plants in their way. They are especially troublesome because they can invade the habitats of many crops.
Armyworms usually have several generation a year, and their capacity to move long distances gives them the power to be the most terrible pests. The damage is most carried out by the larvae which are initially in the form of caterpillars with a special pattern that can change from green to brown or brown to green, with lines running down the back and a characteristic inverted "Y" shape on the head.
The disadvantages of the use of chemical insecticides are the environmental pollution, the harmful effects on the health of humans and animals, the resistance of insects to the chemicals, and the economic cost.
Farmers have usually used chemical insecticides as the main method to fight pest populations. However, these chemicals come with significant downsides:However, these chemicals come with significant downsides:
- Resistance Development: Armyworms are pretty good at developing resistance to chemical pesticides at a really fast speed. Therefore, this resistance can be the reason of the necessity of the development of stronger, more toxic chemicals that will have the negative impact on the environment and human health.
- Environmental Impact: The chemical insecticides usually do not discriminate between the target pests and the non-target species, and thus, the non-target species including the pollinators and the beneficial insects are also declining which in turn leads to the increase in other pests. Besides, they can pollute these chemicals can also contaminate water, soil, and non-target vegetation.
- Health Rispects: The chemical pesticides residue can be found on crops and the environment for long periods, threatening human health, especially for the farm workers and the local communities.
Advantages of the biological control methods are numerous, they do not need any external intervention, they are environmentally friendly, and they do not cause any harm to the non-target species.
Action directed to the area of Bacillus Thuringiensis (Bt) is the name of the study.
Bacillus thuringiensis is a bacterium that produces crystalline proteins (Cry toxins) that are toxic to the insects of many species including armyworms. Through Bt ingested by the larvae, it binds to the specific receptors in the gut which results in the rupturing of the cells and, thus, the death of the insect. This particularity is advantageous because it does not harm other insects like the bees and butterflies which, in turn, are the key factors for pollination.
Sustainable and Safe
Biological control agents such as Bt last for a very short period in the environment, so the problem of long-term environmental contamination is not really a worry. Bt is a non-toxic pesticide that does not harm humans, animals, and beneficial insects which is a great asset for the sustainable farming and integrated pest management.
Biological control which is the use of agricultural agents such as predatory organisms, pathogens, parasites and infections, is a technique of increasingly widely adopted in crop management.
Integration with IPM
Bt is able to be incorporated into the IPM strategies that are based on; crop rotation, planting of pest-resistant varieties, and applying natural predators or barriers. IPM is intended to employ the least toxic and the most environment-friendly methods first, and chemical methods are to be used only as a last option.
Product Selection
The choosing of the appropriate Bt product is the main factor in effective pest control. armyworm treatment insecticide by Novobac which are designed for the particular purposes, are modified for the pests so that they will be able to deal with the armyworms efficiently and will not waste the resources on the agents which are not for that purpose.

is one of the most common methods in today's times. Besides, it can be applied easily, it is affordable, and the environmental impact is quite low.
Conclusion
Novoba,. The decision to employ biological control methods for the management of armyworms in corn and wheat is not only about the effective fight against pests. Besides, it is also about the guarantee of the long-term sustainability, the protection of the ecological balance, and the reduction of the health risks caused by the chemical pesticides. With advanced biological products from armyworm insecticide manufacturers Novobac,the farmers can solve the pest problems in a way that will serve the healthy crops and the environment. Through the application of these methods, they play a great role in the agricultural future, thus the land and the livelihood of the farmers will be able to flourish for generations to come.
