Larvae mainly attack [...] Thirdly, search for the presence of larvae. Small, white maggots near the base of affected bean plants are a clear sign of bean seed fly infestation. Finally [...] The damage symptoms of bean seed fly infestation include: Wilting or yellowing: Infested bean plants may exhibit wilting or yellowing of leaves, particularly

Researched & Discovered In Sweden The origin of Cerall lies at the Swedish University of Agricultural Sciences, where the first preliminary tests [...] isolated no fewer than 400 bacterial strains from the roots of wild and cultivated plants. They then screened these strains for their activity against

In case of severe infection , the heads of wheat become black and the kernels become shrivelled and deformed [...] transmission is also possible. The germ tubes can infect the leaves of the plants directly or through stomata. The lesions become visible after five to [...] optimum temperature for germination of the conidia is between 20 and 25 °C. The ascospores are responsible for wind dispersal of the fungus over longer distances

• Greenhouse whitefly

  The larvae of whitefly need a lot of protein for growth, and thus consume a large quantity of plant sap. This contains a high proportion of sugar, and [...] If the population is very large, feeding on plant sap can affect the physiology of the plant, as a result of which growth is retarded. In full sunlight [...] can be transmitted. The consumption of plant sap and secreting of honeydew by whiteflies reduce the aesthetic value of crops. This is particularly important
