According to the Institute for the Control of Agrochemicals, Ministry of
Agriculture (ICAMA), in 2015, altogether 8 registrations of new fungicide active ingredients (AIs), including 7 technical and 10 formulations, were
approved in China, twice the figure in 2014 and almost the same as 2013. In
particular, five were first registered by domestic enterprises, 62.5% of the
national total, slightly up over 2013 (57%) and 2014 (50%).

Notably, among the 8 new registered fungicide AIs, many were independently
developed by China. This will be favorable for adjusting pesticide structure,
improving competitiveness in the global market, and pushing forward the
sustainable development of pesticide industry.
The five fungicide AIs first registered by domestic enterprises in 2015
included:
B2-a (with independent intellectual property rights)
In April 2015, CAC Nantong Chemical Co., Ltd. (CAC Nantong) obtained two
temporary registrations for B2-a, namely:
98% B2-a TC (registration No.: LS20150091): low toxicity
5%
B2-a EC (registration No.: LS20150102): low toxicity, for cucumber powdery
mildew
So far, CAC Nantong has planned to launch a 100 t/a B2-a EC project.
B2-a is an innovative disease resistance inducer developed by East China
University of Science and Technology. This fungicide, without fungicidal
activity itself, induces crops' resistance to fungi.
Fluoride ether bacteria amide (with independent intellectual property rights)
On 30 July, 2015, Shandong United Pesticide Industry Co., Ltd. (Shandong United
Pesticide) obtained temporary registrations for:
98% Fluoride ether bacteria amide TC (registration No.: LS20150222)
50% Fluoride ether bacteria amide WG (registration No.: LS20150226): for
downy mildew
40% Fluoride ether bacteria amide + hexaconazole SC (registration No.:
LS20150237): for rice sheath blight
Fluoride ether bacteria amide, a new member of the fluorine-enriched benzamide
fungicides, was jointly invented by Shandong United Pesticide and Shandong
Agricultural University in 2010 and patented for invention by the State
Intellectual Property Office.
The two formulations were all launched in 2015, according to Shandong United
Pesticide.
Fenjuntong (with independent intellectual property rights)
On 14 June, 2015, Jiangsu Tenglong Biological & Medicinal Co., Ltd.
(Jiangsu Tenglong) obtained temporary registrations for:
90% Fenjuntong TC (registration No.: LS20150190): low toxicity
40% Fenjuntong EW (registration No.: LS20150187): low toxicity, for rice
sheath blight, expiry date on 14 June, 2016
Jiangsu Tenglong has been authorized two patents for invention on Fenjuntong
and is the exclusive producer. Environmentally-friendly, this fungicide boasts
outstanding efficacy against diseases on crops, like grain, fruit trees,
vegetables and cotton.
β-Sitosterol
On 19, May, 2015, Shaanxi Sunger Road Bio-Science Co., Ltd. (Shaanxi Sunger
Road) obtained temporary registrations for:
0.66% β-Sitosterol TK (registration No.: LS20150137): micro toxicity
0.06% β-Sitosterol ME (registration No.: LS20150138) : micro toxicity,
for rice stripe disease and rice black streak dwarf
β-Sitosterol has strong activity against crop viruses. It changes the activity
of nuclease so as to encumber the synthesis of virus. Moreover, it can also
induce crops' resistance to virus.
So far, Shaanxi Sunger Road has been the exclusive producer of this fungicide.
Coniothyrium minitans
On 22 Oct., 2015, Hubei Xinfeng Crop Protection Co., Ltd. obtained temporary
registration for 4 billion spore/g coniothyrium minitans WP (registration No.:
LS20150312). This low toxicity fungicide formulation is mainly used for rape
sclertiniose.
Among the new fungicide AI registrations in 2015, oxathiapiprolin, metrafenone
and penflufen were developed and registered by foreign enterprises.
Out of the three, oxathiapiprolin is DuPont's new piperidinyl fungicide (with
oxazole, parazole and parazole in the molecular structure) for the diseases
control and prevention on crops like potatoes, grapes and vegetables. This
brand-new fungicide was developed from Merck & Co Inc.'s pharmaceutical
chemical compound (Patent No.: WO2005003128).
Through high-throughput screening
on this chemical compound, DuPont found chemicals with relatively strong
fungicidal activity and developed the oxathiapiprolin fungicide specific to
downy mildew.
Notably, given oxathiapiprolin's sole application (on specific parts of crops
such as leaves) and high risk of resistance, "We plans to launch
oxathiapiprolin fungicide mixtures (like mixing with mancozeb or famoxadone) in
next few years to extend its product life cycle and improve its
performance," said DuPont.
On 19 Dec., 2015, DuPont obtained temporary registrations for 95%
oxathiapiprolin TC (registration No.: LS20150356) and 10% oxathiapiprolin OF
(registration No.: LS20150355). Out of the two, the latter one was registered
for the control and prevention of tomato late blight, cucumber downy mildew,
pepper phytophthora blight, potato late blight and grape downy mildew.
In March 2016, the 10% oxathiapiprolin OF was launched in China and has become
hot in the market, showing Chinese farmers' eagerness towards this new product.
In 2012, 2013 and 2014, registrations of new fungicide AIs in China reached 3,
7 and 4 respectively, namely:
2012: tricyclopyricarb, picoxystrobin and
initium
2013: coniothyrium minitas, dodine,
fenpropidine, fluxapyroxad, meptyldinocap, sphaerotheca amyloliquefaciens and
methiadinil
2014: bacillus firmus, bacillus marinus,
sedaxane and lsopyrazam
Registrations of new insecticides, fungicides and herbicides (by active
ingredient), 2013-2015
