Synthetic Pesticides for Mung Bean: Which Works Best?

Synthetic Pesticides for Mung Bean: Which Works Best?
Choosing the right pesticide can be the deciding factor between a successful harvest and significant crop loss. For mung bean farmers in Rajasthan, insect pests like aphids, whiteflies, and jassids pose a constant threat, capable of devastating yields. While botanical solutions offer a natural approach, many farmers rely on synthetic pesticides for mung bean for rapid and effective control. But with multiple options on the market, which one truly delivers the best results?
This article dives deep into a two-year scientific study that directly compared the effectiveness of two widely used synthetic pesticides against the most damaging mung bean pests. We will break down the data to see which chemical provided superior protection, helping you make a more informed decision for your farm.
The Contenders: Two Widely Used Synthetic Pesticides
The research focused on two specific synthetic insecticides to measure their impact on major mung bean pests. The experiment was designed to determine the “effectiveness of emamectin benzoate 5 SG and thiamethoxam 25 WG against insect pests of mung bean during kharif 2019 and 2020” (p. 121). The goal was to measure the “mean reduction of insect pest population” (p. 121) after application.
These two insecticides were chosen for their common use and distinct modes of action in controlling sucking and chewing pests.
The Battle Against Aphids: Which Pesticide is More Effective?
Aphids are a primary concern for mung bean farmers, and the study meticulously recorded how each pesticide performed against them.
During the 2019 season, after the first spray, Emamectin benzoate demonstrated superior performance. The data showed that “The maximum reduction 80.39 percent was recorded with emamectin benzoate and minimum reduction 70.59 percent was recorded with thiamethoxam” (p. 121). After a second spray, Emamectin benzoate again proved to be the “most effective insecticide… caused 82.06 percent reduction” compared to 69.56% for thiamethoxam (p. 122).
In 2020, the trend continued. After seven days, Emamectin benzoate led to a “maximum reduction 79.46 percent” in the aphid population, while thiamethoxam achieved a “minimum reduction 74.41 percent” (p. 133).
Key Takeaway: For aphid control, Emamectin benzoate 5 SG consistently provided a higher reduction in pest numbers compared to Thiamethoxam 25 WG across both study years.
Whitefly Population Control with Synthetic Pesticides
Whiteflies are especially damaging due to their role in spreading the Yellow Mosaic Virus. Effective control is therefore critical for preserving the crop.
In the 2019 trials, both pesticides were effective, but Emamectin benzoate had the edge. Seven days after the first spray, the “maximum reduction 87.00 percent was recorded with emamectin benzoate. The minimum reduction 82.00 percent was recorded with thiamethoxam” (p. 125). Following the second spray, Emamectin benzoate achieved a staggering “96.36 percent” reduction, while thiamethoxam reached 90.90% (p. 126).
The 2020 results mirrored this pattern. After the first spray, Emamectin benzoate caused an “85.93 percent reduction” compared to 82.03% for thiamethoxam (p. 137). Ultimately, the study found that among the tested options, Emamectin benzoate “was found most effective against whitefly population over untreated control. It was caused maximum 96.36 percent reduction in population of whitefly” (p. 170).
Managing Jassids: A Clear Winner Emerges
The final major pest studied was the jassid. Once again, the data pointed to one pesticide as the more effective choice.
In 2019, after the first spray, the “maximum reduction 80.19 percent was recorded with emamectin benzoate and minimum reduction 73.27 percent was recorded with thiamethoxam” (p. 129). After the second spray, the gap widened significantly, with Emamectin benzoate achieving a “93.02 percent reduction” versus 83.72% for thiamethoxam (p. 130).
The 2020 season confirmed these findings. Emamectin benzoate consistently delivered higher reduction rates, leading to the conclusion that it “was found most effective against jassids population over untreated control. It was caused maximum 92.00 percent reduction in population of jassids” (p. 173).
Conclusion: Data-Backed Pest Management Decisions
After two years of field experiments, the evidence is clear. While both emamectin benzoate and thiamethoxam are effective synthetic pesticides for mung bean, the study consistently found that “emamectin benzoate was found more effective as compared to thiamethoxam against the population of aphid, whitefly and jassid” (p. 202). This research provides invaluable, data-driven insights for farmers seeking the most potent chemical solution to protect their mung bean crops and maximize their yield.
