The Watermelon Fusarium wilt has been such a stressing disease to watermelon farmers for quite some time now. It results in great yield reductions and economic hardships. But, with the help of new and improved biological control methods, the fusarium wilt management of this disease has become efficient as well as ecological. This blog is about the watermelon farmer John Miller from Georgia, who effectively controlled Fusarium wilt through Trianum Shield.
Fusarium wilt is quite a nemesis for us, the people who cultivate watermelon. It is a vil; this disease is due to the fungus Fusarium oxysporum, if this pathogen infects your crops, it’s over. Yes, I have noticed how it gets into the water-vascular system of the plants. This is the one that delivers water and nutrients to these plants and when this is not well developed the plants cannot grow well. They begin drooping, the leaves pale yellow as if they’re suffering from jaundice and it does not take long before the plant is dead.
First thing that I keep looking at is the color of the leaves where the first sign is that the leaves turn yellow. That is perhaps a vague signal but if you pick it up early it might be of great help. After some days, the severity of wilting intensifies and one is able to witness retarded growth of the plants. This is a sad sight especially when you have a good crop all optimized for a good yield at the next stage of growth. If you were to cut into the stem of an infected plant, inside, you’d see a clear sign of trouble: variable from being a plainly brown discoloration of the vascular bundles when observed under low power. That is the characteristic feature of Fusarium wilt.
It is a very difficult disease because the signs are similar to other illnesses affecting plants and therefore one has to be able to discern and know what it is that one is combating. Through my experience, I have discovered that the first strategy of dealing with it is to prevent it, then as soon as symptoms are noticed, act on the issue immediately.
To be specific, John Miller has been farming organic watermelons for more than two decades. Over the years, he was able to identify that yields of his crops have reduced dramatically especially because of fusarium wilt disease. John says, “This year my watermelon plants were all the time giving a pitiful sight of dying as much as I tried my best. ” He did some organic treatments but could not find the kind that would help in solving the issue competently. The disease affected not only the quantity of his output by decreasing it, but also the quality of the output by increasing his production costs.
Undeterred, John went to a workshop on biological control measures only to discover Trichoderma harzianum, used in the Trianum Shield (fusarium wilt control fungicides). Trichoderma harzianum is a friendly fungus that can effectively suppress the crop diseases such as Fusarium oxysporum in Kenya.
The product known as Trianum Shield derived from Trichoderma harzianum outweighs the following advantages to the farmers fighting Fusarium wilt. Interestingly, this causes the plants to be healthier due to the strengthened root systems and general protection against stress. The use of biocontrol agents operate on the principle of a biological dominance over the noxious pathogens and hence minimizes the diseases such as the Fusarium wilt. Trianum Shield for pest control does not have any toxic chemicals and has no residual left behind in the soil and is friendly to beneficial insects and microorganisms. In this way, Trianum Shield assists farmers to receive better yields and higher quality crops and at the same time improve the soil and reduce the extent of chemical fungicides used.
John decided to take his chances and get a try at the Trianum Shield. He ensured that adhered to the application procedures recommended by the manufacturer. Here is how John used Trianum Shield to manage Fusarium wilt in his watermelon fields:
The results were remarkable. John realized that there was an improvement in lessning of Fusarium wilt in his watermelon plants. The plants which were treated were greener, had better vigor, and the leaves did not wilt as those of the untreated plants. Moreover, regarding the yield of watermelons at the end of the season, John received a 40% uplift in yields, and furthermore, he noticed a considerable enhancement of the crop’s health.
John’s success story must be considered in connection with the comprehensive ICM activities. Here are some best practices for controlling Fusarium wilt in watermelons:
– Crop Rotation: One should refrain from planting watermelons or any other crop liable to the disease in the particular field for several years.
– Resistant Varieties: When selecting watermelon, it is recommended to opt for the Fusarium wilt- resistant varieties if available in the market.
– Sanitation: Till and rake to move existing plant debris to decrease the quantity of the pathogen available.
– Soil Health: Soil should be ‘healthy’ through the application of organic matter and adequate or proper water supply.
As it has been established, Fusarium wilt is a very destructive disease that watermelon farmers face but if the farmers are armed with proper equipment and adequate knowledge then the disease can be tamed. This case shows that through use of Trianum Shield and Trichoderma harzianum, John Miller had a glimpse into the possibilities that the biological control of pests affords to Malaysian agriculturists. Such practices also enable the farmers to safeguard the produce, enhance yields, and diminish the application of chemical fungicides.
