In 2020, China MoARA approved 795 pesticides, a significant recovery from 2019 of just 264. 15 pesticides were registered as TC/TK, including 14-hydroxylated brassinosteroid， Indolebutyric acid (IBA)， Benzylaminopurine，24-Epibrassinolide， Gibberellic acid， Naphthylacetic acid，L-glufosinate, Broflanilide, Teraniliprole, Allantoin, Quinotrione, Bromadiolon, Flocoumafen, Clethodim and Bacillus subtilis. 780 formulated pesticides were approved, consisting of 320 single-element formulations and 460 multi-element formulations. Of the 795 pesticides approved, 672 of them were categorized as low toxic, followed by 84 slightly toxic pesticides and 39 moderately toxic pesticides.
Category and Formulation
300 pesticides were registered as herbicide (2 of them can function as both herbicide and plant growth regulator), followed by fungicide(203), insecticide(179), plant growth regulator(59), fungicidal and insecticidal seed treatment(19), acaricide(19, 6 of them can function as both insecticide and acaricide), nematicide(7), molluscicide(4), rodenticide(3), resistant inducer(3), and insect pheromone（1）.
With significant environmental advantages， 300 of the pesticides were formulated as suspension concentrate. Driven by a large number of Glyphosate and Glufosinate producers, 153 pesticides were registered as solid liquid, the most compatible formulation of these non-selective and widely used herbicides. The number of formulation types rose to 29 in 2020, remarking the sustainable innovation in targeted pests and application technology.
As it is becoming increasingly difficult to develop new compounds, agrochemical enterprises are paying more attention to combine different active ingredients to expand pest spectra and mitigate pest resistance:
- 22.17% of the fungicides approved in 2020 were new fungicide mixtures;
- 12% of the herbicides approved were new herbicide mixtures;
- 9.5% of the insecticides approved were new insecticide mixtures
From the above it can be seen that new mixtures have a considerable percentage of the new registration, particularly the seed treatment sector, which accounted for 30.95% of the category. Partly because of the greater R&D investment, partly because that a seed treatment often requires both fungicidal and insecticidal effects, offering a wide choice of different active ingredients.
Popular and New Active Ingredients
Pyraclostrobin was the most frequently registered active ingredient in 2020, with 44 registrations newly approved, followed by Glyphsoate(41), Clothianidin(40), Thiamethoxam(40), Metamifop(32), Glufosinate(29), Fludioxonil(25), Cyhalofop-butyl(23), Abamectin(22), Dinotefuran(20) and Bifenthrin(19).Pyraclostrobin maintained its popularity despite the patent expiry in 2015. Clothianidin and Thiamethoxam became the treatment of sucking pests for many producers.
6 active ingredients were newly approved, consisting of 4 chemical compounds and 2 biochemical pesticides that exempted from TC/TK registration:
- Tetraniliprole registered by Bayer CropScience;
- Tetraniliprole registered Mitsui Chemicals;
- Codling moth pheromone registered by Shenzhen Bioglobal;
- Bacillusamyloli quefaciens AT-332 registered by SDS Biotech;
- Quinotrione registered by Liaoning Cynda;
- Allantoin registered by Shaanxi TPS
The total number of registered pesticides has markedly increased as compared with 2019, but the number of new active ingredients have dropped significantly, representing the increasing difficulty in developing new compound. It should be noted that all the new active ingredients developed by overseas companies were registered concurrently with their debuts in other key markets overseas.
