Dear friends who care about agriculture and food safety, the author is a plant protection practitioner and pesticide agent. For more than half a year, the people have questioned whether the grass should be used for ormosia, further questioned the pesticide safety assessment system, and even extended to the necessity of pesticide use, which is worrying.

As for whether to open the use of herbicide grass as a defoliant, the author believes that consumers and the public have caused misunderstanding and extreme emotions due to asymmetric information. If the government approves the use of grass as a defoliant for grass, it may affect consumers 'confidence in the bean industry. From the perspective of maintaining farmers' livelihood, although the author believes that 2 ppm residue is extremely safe, the author still supports "delaying approval" of grass on bean. So as not to affect consumers 'willingness to buy.

However, the author hopes to discuss the safety assessment, actual safety and demand of pesticide use through this article, hoping that the public can view pesticide use from different angles and avoid stigmatizing pesticides or pesticide review system.

It doesn't matter to the pesticide manufacturer whether or not it's open in ormosia.

In terms of commercial considerations for manufacturers, the amount of ormosia planted in Taiwan is very small, only 6,000 hectares, and the drug has been patented. Many sub-brands compete with each other at a reduced price, and profits are quite limited.

Therefore, if the application of flufenapyr for drying ormosia beans is approved, it will not bring much profit: excluding 10% of farmers who do not use desiccants, the remaining 5,400 hectares will use 3 litres per hectare. Dividing this by the 91 flufenapyr licenses currently approved, it means that a drug dealer with one license can only sell about 178 litres of flufenapyr, and the total profit is likely to be less than $10,000. Therefore, no company will cause social opposition and panic in order to earn more than 10,000 yuan.

The registration of Coxapyr as a drying agent is completely unimportant to drug dealers because it will not bring much benefit. Although it is confirmed to be safe according to the evaluation results of scientific evidence, and even the total amount control of Coxapyr in China is stricter than that of many countries, if it causes social opposition and panic, I would rather appeal to the government to suspend the implementation. However, the author firmly defends the system of pesticide registration review.
