Plant Pathogens

Alternaria alternata detection test kit by using qPCR. Alternaria alternata is a fungus that causes leaf spots, rots, and blights on many plant parts. Usually, the fungus lives in seeds and seedlings and is also spread by spores.

Alternaria cucumerina detection test kit by using qPCR. Alternaria cucumerina is an ascomycete fungus and it is responsible of the alternaria leaf spot. Alternaria leaf spots may cause reduced yield and smaller fruit and it is spread by wind and rain.

Aspergillus flavus detection test kit by using qPCR. Aspergillus flavus is a saprotrophic and pathogenic fungus that colonizes cereal grains, legumes, and tree nuts; causing ear rot in corn and yellow mold in peanuts. Many strains produce significant quantities of mycotoxins, which, when consumed, are toxic to mammals.

Aspergillus niger detection test kit by using qPCR. Aspergillus niger is a fungus. It causes a disease called black mold on certain fruits and vegetables such as grapes, apricots, onions, and peanuts, ornamental plants, and is a common contaminant of food. A. niger is one of the most common causes of otomycosis (fungal ear infections).

Aspergillus species detection test kit by by using qPCR. Aspergillus is a genus of fungi. Some Aspergillus species cause serious diseases in humans and animals. The most common pathogenic species are A. fumigatus and A. flavus, which produce aflatoxin (toxin and a carcinogen), that may contaminate foods such as nuts.

Bacillus amyloliquefaciens detection test kit by using qPCR. Bacillus amyloliquefaciens is a Gram-positive and non-pathogenic soil bacteria closely related to the species Bacillus subtilis. The appearance of both species is so similar that it is not possible the phenotypic differentiation. However, they can be differentiated by a specific PCR assay. B. amyloliquefaciens main interest is their antifungal properties.

Detection test kit of all serotypes of Citrus exocortis viroid species by using qPCR. Citrus exocortis viroid is easily transmitted mechanically. It infects many species in the Rutaceae and a few in the Solanaceae and Compositae. Citrus exocortis viroid is responsible for exocortis disease, other names for the disease are ‘scaly butt’ and ‘Rangpur lime disease’. Disease symptoms develop when infected budwood is grown on susceptible rootstocks, and trees become stunted and yield poorly.

Citrus psorosis virus phylotype 1 detection test kit by using qPCR. Citrus psorosis virus infect Citrus plants, grapefruit, mandarin, orange and tangerine, lemon, pomelo, and lime. External symptoms can be exhibited in leaves, fruit, bark, trunk, roots, and branches. Leaf infection displays chlorotic flecks, or a decrease in chlorophyll/healthy coloring, mottling, and spots; fruit may show ring-like chlorotic areas.

Detection test kit of all serotypes of Citrus psorosis virus phylotype I + II species by using qPCR. Citrus psorosis virus infect Citrus plants, grapefruit, mandarin, orange and tangerine, lemon, pomelo, and lime. External symptoms can be exhibited in leaves, fruit, bark, trunk, roots, and branches. Leaf infection displays chlorotic flecks, or a decrease in chlorophyll/healthy coloring, mottling, and spots; fruit may show ring-like chlorotic areas.

Citrus psorosis virus phylotype 2 detection test kit by using qPCR. Citrus psorosis virus infect Citrus plants, grapefruit, mandarin, orange and tangerine, lemon, pomelo, and lime. External symptoms can be exhibited in leaves, fruit, bark, trunk, roots, and branches. Leaf infection displays chlorotic flecks, or a decrease in chlorophyll/healthy coloring, mottling, and spots; fruit may show ring-like chlorotic areas.

Detection test kit of all serotypes of Citrus Tristeza virus species by using qPCR. CTV causes the most economically damaging disease to the plant genus, Citrus. The virus is transmitted most efficiently by the brown citrus aphid.

Clavibacter michiganensis detection test kit by using qPCR. Currently exist five subspecies of C. michiganensis: insidiosus, michiganensis, nebraskensis, sepedonicus and tesselarius. C. michiganesis subsp. michiganensis and C. michiganesis subsp. sepedonicus are responsible of the main diseases that cause substantial economic losses worldwide by damaging tomatoes and potatoes. C. michiganensis subsp. sepedonicus causes bacterial ring rot disease in potatoes and C. michiganensis subsp. michiganensis is the causative agent of bacterial wilt and canker of tomatos. Other subspecies of C. michiganensis can affect other crops, including corn and alfalfa.

Fusarium oxysporum detection test kit by using qPCR. Fusarium oxysporum is an ascomycete fungus, which many strains within the F. oxysporum complex are pathogenic to plants, especially in agricultural settings. F. oxysporum is not discriminating, they can cause disease in nearly every agriculturally important plant. While collectively, plant pathogenic F. oxysporum strains have a broad host range, individual isolates usually cause disease only in a narrow range of plant species.

Pathogens responsible of brown rot Monilinia fructicola, Monilinia laxa, Monilinia fructigena and Monilinia polystroma detection test kit by using qPCR. Brown rot is one of the most destructive diseases of stone fruits, such as peach, nectarine, apricot, cherry, and plum. Monilia polystroma (formerly lumped into M. fructigena), cause brown rot on members of the Rosaceae. M. fructicola colonizes blossoms, twigs and fruit, primarily on Prunus spp., but also on pome fruit or other Rosaceae. M. laxa can colonize blossoms, twigs and fruit. M. fructigena is primarily a problem on the fruit of apple, pear, and other pome fruits.

Monilinia fructicola detection test kit by using qPCR. Monilinia fructicola is a plant pathogen, responsible for the brown rot in stone fruits. Brown rot causes blossom blight, twig blight, twig canker, and fruit rot. Infected blossoms wilt, shrivel, and become covered with greyish mold. Petals may appear light brown or water-soaked and the blossom does not produce fruit. Dead blossoms may stick to spurs and twigs until harvest, providing a source of spores for the fruit rot phase.

Monilinia fructigena detection test kit by using qPCR. Monilinia fructigena is responsible for the brown rot blossom blight disease that infects many different types of stone fruit trees, such as apricots, cherries and peaches. M. fructigena is primarily a problem on fruit of apple, pear, and other pome fruits.
