Misuse of vegetable fertilizer and its correction

Myth #1: The Quest for Immediate Results Some farmers tend to go for fast-acting fertilizers and pesticides, aiming for quick results. Certain foliar fertilizers that contain hormones or high-nitrogen compounds can show visible improvements within days, which makes them popular among some vegetable growers. However, this rapid growth often comes at a cost. It can lead to imbalances between vegetative and reproductive growth, ultimately reducing yields. Another example is biological pesticides like avermectin or Bt, which work by targeting insect eggs or disrupting their molting process. These products may not show immediate effects, so they are sometimes overlooked by farmers who expect pests to die instantly upon contact. Unfortunately, the overemphasis on quick results often leads to excessive pesticide residues in crops, posing risks to both consumers and the environment. Misunderstanding #2: Chasing New Products Without Understanding Many vegetable farmers are drawn to new pesticides and fertilizers, hoping they will solve all their problems. While newer products may help avoid resistance in certain pests, most are formulated with multiple active ingredients. This can increase the overall amount of chemicals used, leading to plant damage or phytotoxicity. Additionally, some products haven’t been thoroughly tested or promoted, and their long-term effects remain unclear, making them risky choices for farmers who lack proper guidance. Myth #3: Overuse of Pesticides and Fertilizers A common mistake among many vegetable farmers is applying pesticides and fertilizers in excessive amounts—sometimes several times or even ten times more than recommended. This not only raises production costs but also harms the quality and yield of vegetables. Moreover, over-application of chemical fertilizers can lead to soil salinization, which degrades the land and reduces its long-term productivity. Misunderstanding #4: Inappropriate Use of Fertilizers and Pesticides Many farmers struggle to accurately diagnose plant nutrient deficiencies or pest issues due to a lack of knowledge in crop protection and soil management. As a result, they often apply the wrong fertilizers or pesticides, which can worsen the problem instead of solving it. For instance, when a plant lacks one nutrient, another might be mistakenly applied, causing further stress and even "single salt injury," where excess salts harm the roots and reduce plant health. Misunderstanding #5: Mixing Multiple Pesticides Without Caution It’s common for farmers to mix various pesticides with trace elements, insecticides, or fungicides in an attempt to cover multiple issues at once. However, this practice can reduce the effectiveness of each product or even cause harmful interactions. Some combinations may lead to phytotoxicity, damaging crops and reducing yields. Proper understanding of compatibility and application methods is essential to avoid these unintended consequences.
