May 21, 2025Sym-Agro introduces KitoGard for nematode and root disease control
Sym-Agro has released KitoGard, a new soil-applied product that functions as a nematicide, fungicide, bactericide and root growth promoter. Developed for fruit and nut growers, KitoGard offers a biodegradable, MRL-exempt alternative to synthetic chemistries, with broad-spectrum protection and soil health benefits.
KitoGard works by disrupting nematodes, fungi, bacteria and viruses through direct contact and by activating the plant’s own defense mechanisms, a process known as systemic acquired resistance (SAR). The product is designed to improve plant vigor, reduce disease pressure and increase yields across all crop types.
“KitoGard delivers real performance with a softer touch,” Peter Bierma, chief executive officer of Sym-Agro, said in a release. “The secret is in the way that KitoGard helps the plant defend itself and respond to stress. With so few options in fruit crops for nematode control, KitoGard fills a gap in the toolbox.”
KitoGard is powered by chitosan, a natural biochemical compound derived using a biological/enzymatic deacetylation process. With a high degree of deacetylation (95%) and medium-to-low molecular weight, the formulation is designed for maximum efficacy and ease of use.
The product offers a three-way approach to nematode control:
- Direct interference with nematode feeding and reproduction
- Activation of plant defenses to kill nematodes inside root tissue
- Enhancement of beneficial soil microbes that suppress nematode populations
This multi-pronged mode of action is especially important in managing nematodes in perennial cropping systems.
KitoGard also promotes root development by enhancing nutrient uptake and supporting beneficial microorganisms in the soil. According to Sym-Agro, growers using KitoGard can expect stronger root systems, healthier plants and improved crop resilience.
The product can be applied through soil drench, chemigation, drip, micro emitters or foliar spray, offering flexibility across different farming systems. It is labeled for use on all crops and targets a range of soilborne pests and pathogens, including nematodes, bacteria, fungi and oomycetes, as well as viruses.
