Plant Growth Regulators: Navigating Challenges for a Greener Agricultural Future 06-05-2025

SummaryPlant growth regulators (PGRs) in the pesticide industry, once misunderstood and facing challenges, have become core to modern agriculture. Despite a small market share, they have high entry barriers due to strict registration in China. The industry now focuses on systematic solutions. Technological innovations like plant elicitors and "growth - regulation - nourishment" products drive efficiency and eco - friendliness. PGR application is complex, requiring careful local validation. Future development hinges on integrating product innovation and application breakthroughs, with the agrochemical industry shifting towards green and biological methods.

 


In the intricate landscape of the pesticide industry, plant growth regulators (PGRs) have long been mired in cognitive misconceptions and developmental challenges. For years, they were erroneously conflated with fertilizers due to a lack of clear understanding and faced unwarranted skepticism because of the "hormone" label attached to them. However, after years of technological advancements and widespread knowledge dissemination, PGRs have undergone a remarkable transformation from being mere auxiliary components in agricultural production to becoming indispensable core elements within the modern agricultural framework.

 

When compared to traditional pesticide categories such as herbicides and insecticides, the PGR sector operates in a far more demanding environment. It grapples with formidable obstacles, including the high complexity of technological research and development, intricate application scenarios, and stringent industry access barriers. The journey of PGRs' development stands as a testament to resilience and innovation within the realm of agricultural technology.

 

Despite their relatively modest market share within the pesticide industry, PGRs face exceedingly high entry thresholds. China enforces a rigorous registration management system for PGRs, with the registration process for both active ingredients and formulations spanning an extended period of 3 - 4 years. The registration cost for a single product typically ranges from several million to tens of millions of yuan. This high - cost, long - cycle market - entry mechanism directly determines a company's market influence. In the current competitive landscape, the industry has evolved from a mere product - based competition to a battle of systematic solutions. Enterprises are now compelled to establish comprehensive service capabilities encompassing research and development, production, and application guidance to gain a competitive edge in the market.

 

Technological innovation serves as the cornerstone of maintaining competitiveness in the PGR industry. In recent years, a plethora of new categories and technologies have emerged within the PGR field, such as plant elicitors and the integrated "growth - regulation - nourishment" trinity products. These innovations have injected fresh impetus into the industry's development. Rather than simply enhancing the efficacy of individual products, they are propelling the PGR industry towards a trajectory of high efficiency, precision, and environmental friendliness.

 

For instance, plant elicitors work by activating the crop's innate defense mechanisms, achieving the dual benefits of pest and disease control as well as growth regulation, thereby reducing the reliance on chemical pesticides. The "growth - regulation - nourishment" trinity products focus on root - related issues, integrating functions such as nutritional regulation, growth promotion, and resistance enhancement to form an integrated solution that caters to the demands of modern intensive agricultural production.

 

The essence of PGR application lies in the precise regulation of crop growth rhythms, a process fraught with complexity. The activity and performance of PGRs vary significantly across different crop varieties and geographical environments. The optimal dosage and application timing require meticulous verification and fine - tuning. A PGR may exhibit vastly different effects in the hot and humid southern climate compared to the arid northern regions. As a result, PGRs are introduced into new markets with great caution, undergoing a relatively lengthy and meticulous local validation process. This process not only involves verifying the appropriate dosage and its alignment with the crop's phenological stages but also requires a systematic assessment of environmental factors such as soil and climate on the product's efficacy. Consequently, the technical promotion in the PGR industry is characterized by high practicality, a substantial workload, and a lengthy duration.

 

Healthy plant growth and a favorable growing environment are the foundations for PGRs to fully exert their effects. The scientific application of PGRs, the improvement of the growing environment, and the regulation of crop health need to form a synergistic trinity for enhanced efficiency. This is undoubtedly the inevitable direction for the future development of the PGR industry.

 

In the upcoming agricultural technology competition, the PGR industry must focus on the deep integration of "product innovation" and "application breakthroughs." On the one hand, efforts should be directed towards product upgrades and breakthroughs, intensifying research and development in cutting - edge technologies such as "regulator +" (incorporating nanomaterials, DNA - based biological regulation technologies, etc.) to create high - efficiency, safe, and environmentally friendly products. On the other hand, it is crucial to strengthen professional technical service teams, enabling them to work closely with farmers in the fields. By optimizing and refining integrated "regulator +" technical solutions, these teams can provide standardized and digitalized production technical guidance to growers.

 

As the degree of land intensification continues to rise, the agrochemical industry is undergoing a transformation towards green and biological approaches. Enterprises that excel in product innovation and application breakthroughs will set the new benchmarks for defining industry leaders.
