BioNemaGon – use as BioNematicide
BioNemaGon is a BioNematicide based on a naturally occurring isolate of the bacteria Bacillus firmus. Nematodes affecting tomato, cucumber, pepper, garlic and herbs can be suppressed by use of BioNemaGon.
Pre-planting application of BioNemaGon DP / SL at 1-2 Kg / Lt per Acre significantly reduces the nematode populations and the root infestation (galling index), resulting in an overall increase in yield.
1 Kg / Lt BioNemaGon DP / SL and 500 g. of Mollasses or Crude Sugar are mixed in 3 Lt of water and applied to 10 Kg of DeOiled Cake of Soy or Peanuts or any oil seed cake and covered with a cloth and stored for 3 days and applied to soil before soil preparation / ploughing.
The sequential application of BioNemaGon DP / SL at 1-2 Kg / Lt per Acre (method as stated above) after soil fumigation or soil solarization provides enhanced nematode control, when compared to each treatment alone. The thermo tolerance of the bacterial antagonist enables the application of the bionematicide during the solarization period. The combination of BioNemaGon DP / SL with soil solarization significantly reduces the nematode damage to basil, tomato and cucumber crops.
Preplant application of 1-2 Lt of BioNemaGon SL per Acre suitable for drip irrigation delivery, provides an efficient control of nematode population and reduces root damages on tomato and cucumber crops. A mid season, single application of BioNemaGon SL at 1-2 Lt per Acre , significantly reduces the nematode damage on the root system of a tomato crop.
The use of BioNemaGon offers a feasible, environmentally safe biological control treatment which is: i) easily implementable into organic, conventional and integrated control growing systems; ii) allowing a reduction of toxic chemicals input.

Caution on application rate :
The quantity of BioNemaGon required per acre and the number of applications required depend on the infestation level of nematodes. It is suggested that a proper trial is taken by the user to ascertain application rate and number of applications. |

Root-knot is one of the most serious plant diseases in the world. Throughout the world, root-knot disease causes an average annual yield loss of about 5%. The greatest losses however, occur to those who can least afford it, namely, the farmers of underdeveloped countries. Their losses may be as much as 25-50% over a wide area of available farmland. In addition, there are several indirect losses associated with root-knot disease including secondary attack by other pathogens (in combination with other pathogens, root-knot disease can be disastrous); inefficient utilization of fertilizer and water; and high cost of chemical treatment.
The most common parasites causing this disease belong to the Meloidogyne spp. These nematodes have been shown to parasitize more than 3000 plant species including all the main crop families. Root-knot nematodes are found in all climate zones and in most types of soil. They are more active in finding and attacking plants in warm climates than in colder regions. Plants infected by root-knot nematodes display one or both of the following symptoms: root systems are galled, shortened or reduced by rotting; the stems are shortened and thickened, and the leaves do not grow normally.
The most distinctive symptom caused by root-knot nematodes are the galls or knots on the roots. The galls vary in size from a pin head to compound galls of more than 2.5 cm in diameter. They are irregular, spherical or spindle shaped and most often found on tender rootlets. These structures host one to several hundred female nematodes, which remain stationary throughout their life cycle and feed inside the root.
In light of their global economic impact on commercial crops, there is an urgent need to find an efficient way of controlling root-knot nematodes. Until now, chemicals such as methyl bromide or ethyl dibromide have been used to control nematodes. However, development of resistance by the pathogens to nematicidal chemicals, as well as a heightened awareness of short and long term ecological damage caused by these and other chemicals, have increased interest in developing a bio-nematicidal product which acts specifically against its target nematode without causing ecological damage.
