In the heart of the southern farming belt, where tomatoes are a staple crop, a persistent enemy has been wreaking havoc on yields: the scientific name for this bug is likely to be the Silverleaf Whitefly. Despite its small size, which is typical of insects in this order that feed on plant sap, the tomato crop can be severely affected by this invader. For many years, farmers in the region have waged a war against the pest only to discover that conventional chemical solutions actually harm the plants it is trying to protect and in the process helping to build resistance to the pest.
Yet, this cannot be considered as a narrative of gloom. It’s about survival of a group of farmers including one organic tomato farmer who did not lose hope, and sought for an organically acceptable silverleaf whitefly biological control agent from the soil in Beauveria bassiana to manage pests such as Silverleaf Whitefly.
The Farmer’s Struggle: Where There is a Will, There is a Way
Tom Johnson of the third generation in tomato farming has witnessed all the moments a farmer can go through in his lifetime. Their 50 acres farm located at the valleys had been very productive in the past and yielded well. Still, that was only a few years ago and a bane named Silverleaf Whitefly entered his life. “It began subtly,” Tom says, “but a few seasons later, it became a problem,” He found tomato plants were beginning to die and yields declined steadily over the growing season I tried to control the pest by rotating crops, introducing natural enemies of the pest and minor use of chemicals that have undesirable effects on the natural environment. ”
It was not only feeding directly on the plants, but also transmitting plant diseases such as Tomato Yellow Leaf Curl Virus, TYLCV, making it worse. “I was getting a loss of about a third my produce annually and the chemicals affecting the fungal and insect populations in addition to kale fertility,” Jeros explained.
A Turn Towards Biocontrol: Information About Beauveria Bassiana
Tom first heard about Beauveria bassiana in agriculture during one of the conferences related to farming. A good organic farmer told me how he had used this fungus to eliminate another pest in his fruit farm. Thus the journey of Tom started and he discovered Beveria WP as a biocontrol solution that is derived from Beauveria bassiana.
Beauveria bassiana is a predatory soil fungus that increases its action in terms of pest control on insect pests like the Silverleaf Whitefly. So as soon as it is in touching with the insect, the fungus enters the exoskeleton of the host, multiplies within the host and then the host is killed. It also controls the pest population effectively and is less likely to be resisted unlike the chemical pesticides mostly used in farming.
Politely convinced by the possible environmental friendly method, Tom decided to try.
Implementing Biocontrol: An outline for the framework, based on Carroll and Carson’s punctuated work life concept, including its key components and implementation process is as follows:
Tom began with incorporating Beveria WP in his IPM, as a component of it. Here’s how he did it:
- Monitoring and Timing:Tom also emphasizes that to achieve the best results with Beauveria bassiana products, it is necessary to apply it at the early signs of the whitefly presence: ‘‘This is why I constantly controlled the density of whiteflies in the greenhouse. ’’ This simply meant that he had to plan and time the application of the chemicals through a schedule of inspections of the tomato plants.
- Application:As for tomato hornworms, Tom foliar-applied Beveria WP, a naturally occurring fungus, with a sprayer during early morning or late evening because of lower temperatures. “This way the fungus is given the maximal opportunity to infect the whiteflies before the sun becomes unbearable,” he said.
- Consistency:Tom re-coated the plants following the manufacturer’s instruction and this covered all the plants well especially during the times with a lot of whiteflies. He also changed other biocontrol measures to ensure the flora and fauna of the area were harmonised.
- Cultural Practices:In addition to fungal applications, Tom persisted in the specific cultural management measures like crop rotation and introducing the trap crops in hope for decrease the whitefly population.
The Results: From the organizations’ holistic approach, it becomes evident that MCC’s objective was to support the development of a healthier and more resilient farm.
The results were encouraging. This is how Tom narrates his experience, ‘I observed a reduction in the whitefly population within the first few weeks after the first application. ’ The plants were much more vigorous, and the fruit was setting well There were no indications of yellowing and stunted growth that used to affect my crops in the previous years.
Moreover, Tom was able to discover that due to his form of integrated pest management, the reserve health of his soil actually increased. Many ‘bad’ organisms were eliminated due to the lack of chemicals; thus, making the farm environment more stable and stronger to infestations. In this regard, the words that emanate from his lips are: ‘It has been truly a game changer for me’. With the whiteflies I am not only combating a nuisance, I am also establishing the root for greater development of future crops that can produce and supply food for countries in need.
The Broader Impact: The focus of a sustainable future is to ensure that the economic practices can be sustained and not hindered by the environmental conditions.
Due to the result that Tom has achieved over Beauveria bassiana, other farmers within that region have followed suit to use biocontrols. Ms. Dr. Emily Carter who is working on sustainable agriculture has also explored the umbrella effects of Beauveria bassiana in the region. Ultimately, Dr. Carter concludes, ‘What is being witnessed is gradual change toward the innovation of sustainable practices in farming’. Farmers such as Tom are at the forefront in proving that it is not true that pests have to be eliminated through a method that harms the soil or the food being produced.
In this regard, a plethora of farmers are shifting to smart solutions, such as Beveria WP, in an attempt to restore the tomatoes’ sustainable farming. It is indeed the kind of prospect that bodes well for not just sustaining but actually steadily growing the largely agriculture-dependent community.
For Tom Johnson and many other people it was rather hard to become closer to the dreams of sustainable pest control, although the results speak for themselves. But what is the movie actually about? Tom is Heavy-hearted: It’s not just about tomatoes. Namely, is is about doing it good for the land, good for the community and good for the future.
With more farmers adopting these natural practices the future of tomato farming in this area is as bright as day.
