Joe Sgro Testimonial
Clubroot and nematode have disappeared.
Joe Sgro of Colac in South Western Victoria. Joe Sgro is an organic farmer who has been using Bactivate on farm for the last three years. Joe began using Bactivate on his property after he heard that it may help to reduce the effects of clubroot disease on his crops. Joe told us that before using Bactivate, clubroot disease was causing damage throughout his crops, with losses of up to 80% in some cases.

One of the main issues for Joe was that the nematode infestation he had in his soil exposed his crops to clubroot disease. Clubroot is a disease of cabbages, radishes, turnips, and other plants belonging to the family Cruciferae (mustard family). The disease causes the root system to swell and makes it difficult for the plant to uptake its requirements from the soil.

It was after applying Bactivate at the rate of one 25kg bag of Bactivate to four 25kg bags of fertilizer for four months, that Joe noticed some startling results and first called us out to have a look.
What we found was a drastic change in the root system of cabbages grown on what Joe described as his “roughest piece of land”. Where Joe would often find plants effected by clubroot, he was now finding healthy root systems and an abundance of soil life, particularly worms.
Bacillus Thuringiensis is one of the beneficial bacteria in Bactivate. This particular member of the Bacillus family has a great method for limiting parasites around plants. The Thuringienisis bacteria has the capacity to secrete a crystalline structure which is eaten in turn by by parasites such as nematodes. The ingested crystalline structure then paralyzes the nematode’s stomach, the parasite feels full, stops feeding and dies of starvation.
Without a nematode infestation the cycle of clubroot stops and the plant can get on with growing. When nematodes feed on plant root systems they allow easy access for plant diseases such as clubfoot to get into the root system.
A buildup of Bacillus Thuringiensis around the plant and its root system gives the plant a much healthier defence mechanism than pesticides and herbicides.
