In July 2021, KAOADJUVANTA-200, a special anti flight additive for plant protection UAV developed by Japan Kao Co., Ltd., will be officially listed in China. When used together with pesticides, the product can significantly improve the application effect of UAVs and effectively reduce the use of pesticides. The launch of Kao's new anti fly additives will help the green and sustainable development of agricultural production, and make a positive contribution to improving pesticide application efficiency and reducing environmental load.
Supported by the national policy of "accelerating agricultural modernization", "smart agriculture" supported by digital technology has become the direction and trend of industry development. At present, agricultural UAVs play an important role in sowing, spraying, environmental monitoring, data collection and other aspects, which can greatly improve the efficiency of agricultural production while reducing the burden of personnel. However, in the field of unmanned aerial vehicle (UAV) application with large workload, there are widespread phenomena such as liquid medicine drift and evaporation, which lead to the reduction of efficacy and waste of pesticides. It has become a new topic for modern agricultural development to break through the inherent limitations and achieve accurate application of drugs and resource conservation.
In the field of research and development of functional flight defense additives, Kao has more than 50 years of experience, and has continuously introduced new technologies and products, ranking first in the Japanese market share. In order to meet the needs of China's intelligent agricultural production, Kao has introduced powerful anti evaporation, anti drift, and sedimentation specific anti flight additives to bring efficient and feasible solutions for UAV anti flight operations, and promote food production and environmental protection.
Double technology support high efficacy guarantee
During the application process of UAV, the spraying of liquid medicine is greatly affected by wind and temperature. Rapid evaporation and pollution of non target crops are the main problems faced by the industry. The newly launched KAOADJUVANTA-200 uses Huawang's unique "evaporation inhibition technology" and "spreading enhancement technology" to directly hit the pain prevention points, which significantly improves the prevention effect after application.

The characteristics of "KAOADJUVANTA - 200" ① Using the evaporation suppression technique, inhibition of pesticides to the drift of non-target crops
By using the technology independently developed by Huawang, the surfactant can form a film on the surface of the droplet to prevent the droplet from directly contacting the air, so that it is not easily affected by the surrounding environmental factors, so as to achieve a good effect of anti evaporation and anti drift, and effectively protect the environment outside the operation area.

Characteristics of "KAOADJUVANTA-200" ② Use "spreading improvement technology" to greatly improve the spread of pesticides on crops
The traditional technology is to reduce the surface tension of liquid medicine to improve its extensibility on crops. But Kao also focuses on the "interfacial tension" between the crop surface and the liquid medicine. It is envisaged that the surface tension and the interfacial tension will be reduced simultaneously through the surfactant, so that the affinity between the liquid medicine and the crop surface can be improved. Therefore, "liquid medicine spreading and upgrading technology" has been developed. At the same time, the "liquid medicine spreading and upgrading technology" has changed from the traditional technology that only reduces the surface tension of liquid medicine. The surface tension of liquid medicine and the interfacial tension between liquid medicine and crop surface are reduced simultaneously through surfactant, thus greatly improving the affinity between liquid medicine and crop. Under the same environmental conditions, when KAOADJUVANTA-200 auxiliary agent is added for application, the coverage rate of solution on crops is about 9 times higher than that without the auxiliary agent.
Inhibit the drift of liquid medicine
Improve expansibility
Green benchmark of reducing medicine without reducing effect
Thanks to the greatly improved expansibility, the customer cooperated with KAOADJUVANTA-200 with a small dosage, and its application effect was consistent with the original dosage. In 2020, Huawang and Professor Xu Wenping of East China University of Science and Technology conducted relevant tests in Guangdong. The results showed that after adding KAOADJUVANTA-200, the amount of pesticides decreased by 70%, and the effect of pest control was still similar to that before the reduction.

*1) Test conditions: Test site: Duhu Town, Taishan City, Jiangmen City, Guangdong Province; Target crops: rice; Control objects: rice leaf roller; Water consumption: 1.5L/mu; Kao additive: 2%; Implementation time: September November 2020
*2) Test method: investigate the pest status after twice application
During the 13th Five Year Plan period, the Declaration on Zero Growth of Pesticides in China launched by the Ministry of Agriculture and Rural Affairs received positive responses from the whole industry. After five years of policy implementation, the goal of reducing the amount of chemical fertilizers and pesticides in China has reached the expectation, which has promoted the high-quality development of the planting industry. In the next five years, the Ministry of Agriculture and Rural Affairs plans to increase the utilization rate of chemical fertilizers and pesticides by another 3 percentage points to promote the transformation of the agricultural production mode to a comprehensive green one. The listing of KaoADJUVANTA-200 will provide strong technical support for the realization of this goal.
Under the general trend of intelligent, labor-saving and reduced pesticide application, KaoadJUVANTA-200 auxiliary agent has solved the difficulties of easy evaporation, easy drift and not easy sedimentation of the liquid medicine, making UAV flight prevention work enter a new stage. With the global promotion of this technology, Kao will continue to make contributions to food production and environmental protection.
