Pesticides - Fact Sheet for Microbial Fungicides Boscalid
What is Boscalid?Boscalid is a broad spectrum fungicide used in agriculture to protect crops from fungal diseases.Cas188425-85-6 Boscalid is a systemic fungicide the compound is an biphenyl amide derived inhibitor of succinate dehydrogenase.Boscalid is a new type of niacinamide fungicide, it is mainly used to prevent and control powdery mildew, grey mould, various rot, brown rot and root rot.
Boscalid is a pyridinecarboxamide obtained by formal condensation of the carboxy group of 2-chloronicotinic acid with the amino group of 4'-chlorobiphenyl-2-amine. A fungicide active against a broad range of fungal pathogens including Botrytis spp., Alternaria spp. and Sclerotinia spp. for use on a wide range of crops including fruit, vegetables and ornamentals. It has a role as an EC 1.3.5.1 [succinate dehydrogenase (quinone)] inhibitor, an environmental contaminant, a xenobiotic and an antifungal agrochemical. It is a member of biphenyls, a pyridinecarboxamide, a member of monochlorobenzenes and an anilide fungicide. It is functionally related to a nicotinic acid.
Boscalid It has a broad spectrum of bactericidal activity and has a preventive effect, being active against almost all types of fungal diseases. It has excellent effects on the control of powdery mildew, gray mold, root rot disease, sclerotinia and various kinds of rot diseases and is not easy to produce cross-resistance. It is also effective against the resistant bacteria to other agents.It has a significantly higher control efficacy than carbendazim.
What is the mode of action of boscalid?
Boscalid is a new broad-spectrum fungicide belonging to the class of carboxamides (succinate dehydrogenase inhibitors). It is effective against different stages of fungal development, mainly against spore germination, germ tube elongation but inhibits also other stages such as appressoria formation or mycelial growth.
Succinate dehydrogenase inhibitors (SDHI) of this type act by binding at the quinone reduction site of the enzyme complex, preventing ubiquinone from doing so. As a consequence, the tricarboxylic acid cycle and electron transport chain cannot function.
Boscalid is a kind of mitochondrion respiration inhibitor, being the inhibitor of the succinate dehydrogenase (SDHI) that acts by inhibiting succinate coenzyme Q reductase (also known as complex II) on the mitochondrial electron transport chain, with its mechanism of action being similar as that of other kinds of amide and benzamide fungicides. It has effects on the entire growth period of the pathogen, especially having a strong inhibitory effect against the spore germination. It also has excellent prophylactic effects and excellent intra-leaf permeability.
Boscalid is a foliar application germicide, which can penetrate vertically and be transmitted to the top of the plant leaves. It has excellent preventive effect and has certain therapeutic effect. It can also inhibit the spore germination, germ tube elongation and attachment formation, and is effective in all other growth stages of the fungus, exhibiting excellent resistance to rain erosion and persistence.
How about effect Boscalid
Boscalid is a nicotinamide fungicide with a wide bactericidal spectrum and preventive effect. It is active against almost all types of fungal diseases. It is very effective for various rot diseases, and it is not easy to produce cross-resistance. It is also effective for other chemical-resistant bacteria. It is mainly used for the prevention and control of diseases including rapeseed, grapes, fruit trees, vegetables and field crops.
Boscalid has obvious control effect on Sclerotinia sclerotiorum, and the control effect on diseased plant rate and disease index can reach more than 80% when it is applied at the right time, which is better than other agents currently popularized and applied, and significantly higher than multi-bacteria The anti-effect of the spirit. Use 50% boscalid water-dispersible granules to prevent and control rape sclerotinia, and use 24-36 grams per mu in general years, and 36-48 grams per mu in severe years.

How to Usage Boscalid
Boscalid has fungicidal effects against a wide range of crop pests. These include Alternaria, grey mold (Botrytis cinerea), white mold (Sclerotinia sclerotiorum), and powdery mildew (Uncinula necator). As a result, it has use in crops including fruits, soybeans and vegetables.
The estimated annual use of boscalid in US agriculture is mapped by the US Geological Survey and shows that it is mainly applied to fruit crops, with a maximum use of over 600,000 pounds (270,000 kg) in 2016.Global sales in 2014 were estimated at $390 million. The compound lacks full control of important cereal diseases, especially septoria leaf blotch Zymoseptoria tritici, which has limited its potential.
What is the use of boscalid fungicide?
Boscalid is a fungicide consisting of two formulated end-use products for use on food crops. The wettable granule (WG) Endura Fungicide contains 70% active ingredient, and the wettable granule
(WG) Pristine contains a mixture of boscalid (25.2% active) and pyraclostrobin (12.8% active).
