From "feeling based" to "looking at data": How can portable pesticide residue meters rewrite the safety rules of the vegetable market?

In the field of food safety supervision, the widespread application of portable pesticide residue detectors is profoundly rewriting the safety rules of traditional vegetable markets. From the "feeling based" mode relying on experience judgment to the scientific management relying on precise data, this transformation not only improves detection efficiency, but also builds a food safety protection network covering the entire chain. Among them, Shandong Lanende Intelligent Technology Co., Ltd. has become a core force driving industry transformation through technological innovation and scenario based solutions.

In the past, the regulation of pesticide residues in the vegetable market mainly relied on manual sampling and empirical judgment. Vendors lack self inspection capabilities, and regulatory authorities are limited by the long cycle and high cost of laboratory testing, which often leads to the discovery of problematic agricultural products in circulation. For example, a certain agricultural market once caused dozens of people to suffer from food poisoning due to the failure to detect excessive pesticides in leafy vegetables in a timely manner, exposing the lag of traditional regulatory models. In addition, frequent trust crises among consumers regarding the safety of agricultural products have further exacerbated the conflict between market management and operators.

Through three core technological innovations, Lanende has condensed laboratory level testing capabilities into portable devices, achieving "on-site inspection and data visualization":

Fluorescence immunoassay technology:

The fluorescent pesticide residue detector adopts the principle of antigen antibody specific reaction, and generates signals by binding fluorescent labeled antibodies with pesticide residues. It can accurately identify more than 30 common pesticides such as Fusarium oxysporum and Bactrobin. This technology has a sensitivity of 0.01mg/kg, a detection limit far below the national standard, and does not require complex preprocessing. Single sample detection can be completed in 10 minutes.

Multi channel parallel detection system:

The Lanende LD-QNC2 fully automatic 4-pin detector is equipped with a 12/24 channel independent detection module, supporting the simultaneous processing of multiple samples. At a large agricultural market in Jinan, regulatory personnel used this equipment to complete 200 batches of fruit and vegetable sampling within 2 hours during the morning rush hour, which is 15 times more efficient than traditional methods.

Intelligent data management platform:

The device is equipped with an Android system and a 4.3-inch IPS high-definition screen. The operating interface adopts visual process guidance, and vendors can complete the detection through voice prompts. The detection data is automatically uploaded to the cloud monitoring platform, generating electronic reports containing pesticide types, residue levels, and exceedance levels, supporting QR code traceability and real-time warning.

Lanende deeply embeds portable pesticide residue meters into various stages of agricultural product circulation through customized solutions

Source control of production base:

At the Shouguang vegetable base, the Lanende LD-NC24 rapid detection instrument has become a standard equipment for farmers' "pre planting detection". The equipment can detect residues of pyrethroid pesticides in soil and guide scientific drug use. The data shows that after using this device, the pesticide usage in the base decreased by 37%, and the exceedance rate decreased from 8.2% to 0.5%.

Dynamic supervision of wholesale markets:

Guangzhou Jiangnan Fruit and Vegetable Wholesale Market has introduced the Lanende multi parameter detector to achieve "on-site inspection". The device supports synchronous detection of multiple indicators such as organic phosphorus, amino acid esters, and heavy metals, and forms a "5-minute response circle" in conjunction with a mobile detection vehicle. In the first half of 2025, the market intercepted 12 tons of problematic agricultural products, a decrease of 62% compared to the same period.

Empowering retail end consumers:

The supermarket has set up a Lanende LD-SP06 self-service testing station in the fruit and vegetable area, where consumers can scan the code for free testing. The device adopts a large screen display and voice broadcast function, with a success rate of 98% for the elderly population. Since its launch in March 2025, it has provided testing services to consumers over 50000 times, with a 21% increase in repurchase rate.

The popularization of portable pesticide residue meters by Lanende brings multidimensional social benefits:

Economic aspect: Reduce the loss of unsold agricultural products caused by excessive pesticide residues. According to calculations, the single vegetable market can avoid economic losses exceeding 2 million yuan annually.

Regulatory level: Establish a three-level prevention and control network of "grassroots self inspection+superior sampling+cloud supervision". According to data from the Shandong Provincial Food and Drug Administration, the qualified rate of pesticide residues in agricultural markets in the province has increased from 92% in 2020 to 99.3% in 2025.

Cultural aspect: Rebuilding consumer trust through "transparent testing". After the introduction of Lanende equipment in a community vegetable market in Nanchang, the passenger flow increased by 35%, becoming a national demonstration point for "smart vegetable farms".

From "relying on intuition" to "looking at data", the Lanende portable pesticide residue analyzer is not only a technological revolution, but also a modern transformation of the food safety governance system. When every vegetable carries a "digital ID card" and every inspection becomes a traceable trust certificate, the Chinese vegetable market is moving towards a new era of security and intelligence.
