For long, streptomycin was widely used for controlling and preventing bacterial diseases. Yet, after 2016, it will be banned in China. In this context, many other bacterial products compete for the large market share used to be taken up by streptomycin. Changes are expected to take place in the domestic bacterial fungicide market in the near future.

So, what are the main bacterial fungicides in the market to date? And which are the leading producers?

According to the Institute for the Control of Agrochemicals, Ministry of Agriculture, major bacterial fungicides registered in China include thiediazole copper, bismerthiazol, paenibacillus polymyza, pseudomonas fluorescens, bacillus subtilis, chloroisobromine cyanuric acid, trichloroiso cyanuric acid, zhongshengmycin, ethylicin, kasugamycin, shenqinmycin, copper hydroxide, copper oxychloride, bordeaux mixture, copper calcium sulphate, copper (succinate + glutarate + adipate), copper acetate, Zn-thiodiazole and saisentong.

It is notable that both domestic and overseas pesticide manufacturers compete for larger sales in the Chinese bacterial fungicide market. According to complete statistics, leading enterprises were:

• Domestic: Zhejiang Longwan Chemicals Co., Ltd. (thiediazole copper), Zhejiang Xinnong Chemical Co., Ltd. (Zn-thiodiazole), Nanjing Nannong Agriculture Science and Technology Development Co., Ltd. (chloroisobromine cyanuric acid), Hunan Wanjiafeng Technology Co., Ltd. (copper rosinates), Jiangxi Heyi Chemical Co., Ltd. (copper oxychloride), Zhejiang Hisun Chemical Co., Ltd. (oxine-copper) and Yanbian Chunlei Biologicals Co., Ltd. (kasugamycin)

• Overseas: DuPont (copper hydroxide), Nufarm Limited (copper hydroxide) and Industrias Químicas del Vallés, S.A. (copper calcium sulphate)

Specifically, common bacterial fungicides are categorised as follows:

1. Organic copper

• Advantage: good efficacy, compatibility and high safety; little phytotoxicity

• Disadvantage: expensive

• Application: long duration for use, even applicable during flowering and early-fruiting periods; wide spectrum, including rice, vegetables, melons and fruits

Given these features, this kind of fungicides develops rapidly in the market, even though it has not been launched for long. Moreover, given its high value for research, organic copper fungicides are promising in the market. In particular, thiediazole copper, a member of this series, is widely used now.

2. Inorganic copper

• Advantage: high efficiency and low price

• Disadvantage: easy to cause phytotoxicity; not applicable during flowering and early-fruiting periods or just in restricted amount; poor efficacy; difficult to be applied on rice

As a traditional product, inorganic copper fungicides show week profitability and producers have to face intense competition in this market. Notably, some enterprises also launched new inorganic copper formulations that show strong fungicidal activity, long-lasting efficacy and safety to crops.

3. Antibiotics

• Advantage: widely used; systemic; good efficacy

• Disadvantage: strong resistance as the kind of products has been used for long; low safety as residues may pose risks to human life

• Application: specific usage methods should be chosen based on crop diseases

So far, antibiotic fungicides are restricted by national policies on registration, residue limits and antibiotics abuse. In particular, streptomycin, a typical product in this family, will be banned for registration after 2016.

4. Thiazole
Thiazole fungicides were first used for the control and prevention of rice bacterial leaf blight which is no longer a serious disease now. As the planting area of cash crops expands and bacterial diseases strike more often in recent years, the kind of products becomes popular again in the market.

The products have limited efficacy against bacteria in soil given the fact that they show no fungicidal activity when separated from crops.

5. Microbial formulations

• Advantage: environmentally friendly; able to improve soil quality; safety to crops. animals and human

• Disadvantage: low recognition among farmers

So far, these innovative formulations are popular in production bases for pollution-free vegetables, exported vegetables and organic food.

Bacterial diseases, caused by bacteria or fungi, are often induced by high temperature and humidity.

• Symptom: wilting, rotting and perforating; stench mucus exuding from infected areas in wet weather

• Category: leaf spot, leaf blight, leaf wilt, canker, rot and deformity

In reality, common bacterial diseases include cucumber angular leaf spot, pepper bacterial wilt, tomato bacterial wilt, Chinese cabbage bacterial soft rot, potato ring rot, citrus canker, peach bacterial shot hole, fruit tree crown gall, etc.
