Some embodiments are directed to systems, methods, and formulations containing chitosan encapsulated nanoparticle pesticides. The nanoparticle solutions may contain one or more of garlic oil, clove oil, thyme oil, spearmint oil, geraniol, oxymatrine, soapbark oil, neem oil, castor oil, lemongrass oil, cedarwood oil, cinnamon oil, rosemary oil, peppermint oil, lavender oil, lemon oil, citrus oil, lemongrass oil, sesame oil, safflower oil, tea tree oil, or other essential oils with concentrations ranging from 50 to 4000 ppm. The pesticides may be used to control root-knot nematode, cyst nematode, root-lesion nematode, burrowing nematode, dagger nematode, spiral nematode, wilts, rots, blights, cankers, mites, thrips, aphids, whitefly, mealybug, gnats, slugs, midges, leafhoppers, skeletonizes, psyllids, flies, ants, and others. The nanoparticle formulations are encapsulated in a chitosan solution to create chitosan encapsulated slow-release pesticides.

Some embodiments include a method of chitosan encapsulation of pesticidal active ingredients. The method includes adding a first active ingredient to a centrifuge, adding a solution containing chitosan into the centrifuge, centrifuging the chitosan-active ingredient mixture to create nanoparticle spheres of a first diameter, collecting the nanoparticle spheres of a first diameter, adding the nanoparticle spheres, a second active ingredient, and a chitosan solution into a centrifuge, and centrifuging to create nanoparticle spheres of a second diameter larger than the first diameter, and collecting the nanoparticle spheres of a second diameter.

Some embodiments are directed to a system for a formulation of nanoparticles used for protecting plants from pests while promoting plant growth. The system includes a solution with a filler, an extender, a wetting agent, a disintegrant, or a surfactant, and nanoparticles with spherical layers in the solution. The nanoparticles contain a spherical liquid core layer comprising a pesticidal active ingredient, a spherical first layer comprising chitosan, the spherical first layer wrapping the spherical liquid core layer and located directly on the spherical liquid core layer, a spherical second layer comprising a fertilizing active ingredient, the spherical second layer wrapping the first spherical layer, and a spherical final layer comprising chitosan, the spherical final layer being the outermost spherical layer of the nanoparticle. The formulation is applied to an environment, and the pesticidal active ingredient and the fertilizing active ingredient are released into the environment.

The present invention relates to novel triazole derivatives of formula (I) having insecticidal activity, to processes and intermediates for preparing them, toinsecticidal, acaricidal, nematicidal or molluscicidal compositions comprising them and to methods of using them to combat and control insect, acarine, nematode or mollusc pests (I) wherein X.sub.0, X.sub.1, X.sub.2, Y.sub.1, Y.sub.2, R.sub.1, R.sub.2, G.sub.1 and G2, and Q are as described in formula 1 or salts and n-Oxides thereof.
