Plant growth regulators help reduce pesticide use
Plant growth regulators, known as "small products with great benefits", have been increasingly valued in recent years for their important role in increasing crop yields and efficiency, simplifying labor, improving quality, making up for the lack of economic traits, and improving stress resistance. The 5th Plant Growth Regulator Development and Application Exchange Conference, hosted by the China Pesticide Development and Application Association, was held in Chongqing recently. Many experts in this field shared and exchanged new progress, new achievements, and new demands in the research and application of plant growth regulators.
The industry leaders and experts attending the conference fully affirmed the role and potential of plant growth regulators, believing that although the dosage is small, the efficacy is outstanding and the application prospects are broad. It is recommended to strengthen the guidance of the use of technology, promote accurate and standardized use, and especially strengthen the integrated use of other green production technologies, which will play a greater role in ensuring efficient agricultural production and agricultural product quality and safety, and promoting the zero growth action of fertilizer and pesticide use. Improve plant stress resistance.
Liu Yongquan, president of the China Pesticide Development and Application Association, said that plant growth regulation technology and the use of plant regulators are becoming one of the most active professional fields in modern agricultural production, and their contribution to agricultural progress is constantly increasing. Whether plant regulators can be used scientifically, reasonably, correctly and in a standardized manner has gradually become an obvious sign to test and measure the degree of precision and accuracy of farmers' planting techniques. In practice, the understanding of the efficacy of regulation technology has been continuously deepened, and more and more single products or combined use, as well as the resulting crop solutions, have benefited the majority of growers.
Liu Yongquan suggested that production enterprises should focus on resource integration, independent innovation, and technical services, strive to improve product quality, standardize product instructions, accelerate the registration of plant growth regulators on specialty small crops, and provide high-quality and efficient plant growth regulator products. The competent departments of the industry should formulate an industrial development plan for the entire industry, and guide the orderly development of the industry through policy guidance and support. At the same time, we should unite multiple forces to do a good job in popular science publicity and technical guidance services.
There is still potential to be tapped
"Plant growth will encounter many adverse conditions that are not conducive to growth, such as late spring cold and drought, and there is an urgent need for efficient, safe and stress-resistant plant growth regulators." Research and experiments have found that oligosaccharide regulators can improve the disease resistance and cold resistance of crops, promote growth, and improve crop quality. He believes that in the "fertilizer and pesticide reduction" action launched in my country, oligosaccharide plant stress resistance inducers can play a great role, have a large application space, and will play an important role in green agriculture.
"The integrated use of green plant protection technology, mainly using immune inducers, makes up for the shortcomings of using a single product and has achieved good application results. We are very confident that the use of chemical pesticides can be reduced by 30%." Tan Hong, a researcher at the Chengdu Institute of Biology, Chinese Academy of Sciences, said that her team also used immune inducers in conjunction with biofungicides, insecticides, natural enemies of pests, physical control technology, and low-toxic green chemical pesticides to establish a green plant protection technology integration and for a variety of crops, with significant effects in reducing pesticide use and increasing efficiency and promoting quality and safety.
Accurate use is important
Many experts pointed out that because plant regulators have high biological activity and need to accurately control their usage, it is particularly important to strengthen correct professional guidance during use.
In practice, plant regulators fail to achieve the desired effect, which is due to factors of the crop itself, as well as factors of the agent, environment, and human factors. In addition, some growers arbitrarily increase the dosage or concentration, use products that have not been registered as pesticides, or use illegal products that may contain "invisible ingredients" or "use fertilizers as medicines", which are unscientific and non-standard. Not only is it difficult to achieve the expected effect, but it may even cause pesticide damage and unnecessary production losses.
“Plant growth regulators have unique effects, are safe and efficient, have great potential, and are small products with great value. They play an irreplaceable and important role in modern agriculture. This has become an industry consensus.”
