The present invention provides pest control formulations which comprise lignin as well as methods of protecting pest control agents from environmental degradation through the use of lignin. A solubilized lignin solution is prepared by mixing water, lignin, and a pH adjuster to form a solubilized lignin solution having a pH of between about 7 and about 12, preferably between about 8 and about 11, and most preferably between about 9 and about 10. The solubilized lignin solution is then used to prepare the pest control formulation by mixing with pest control agent and a multivalent salt and drying to form a dispersible formulation. The dispersible formulation is mixed with water to form the pest control formulation having resistance to solar degradation. Alternatively, the solubilized lignin solution may be used as an adjuvant by drying and later adding the dried adjuvant to pest control agent and a multivalent salt to form the pest control formulation, or by mixing directly with pest control agent and multivalent salt to form the pest control formulation. When prepared with the lignin adjuvant, the pest control formulation has improved resistance to washoff as well as resistance to solar degradation.

La présente invention concerne des formulations de lutte anti-parasite comprenant de la lignine, ainsi que des procédés de protection d'agent de lutte anti-parasite contre la dégradation environnementale par l'utilisation de lignine. On a préparé une solution de lignine solubilisée par mélange d'eau, de lignine et d'un ajusteur de pH afin de former une solution de lignine solubilisée d'un pH compris entre environ 7 et environ 12, de préférence entre environ 8 et environ 11, et idéalement entre environ 9 et environ 10. On utilise ensuite la solution de lignine solubilisée afin de préparer la formulation de lutte anti-parasite par mélange avec un agent de lutte anti-parasite et un sel multivalent, puis par séchage afin de former une formulation dispersible. On mélange la formulation dispersible à de l'eau afin de former la formulation de lutte anti-parasite présentant une résistance à la dégradation solaire. Dans un autre mode de réalisation, on peut utiliser la solution de lignine solubilisée en tant qu'adjuvant par séchage et ensuite addition de l'adjuvant séché à un agent de lutte anti-parasite ainsi que d'un sel multivalent afin de former la formulation de lutte anti-parasite, ou par mélange directement avec un agent de lutte anti-parasite et un sel multivalent pour former la formulation de lutte anti-parasite. Lorsqu'on la prépare avec l'adjuvant de lignine, la formulation de lutte anti-parasite présente une résistance améliorée au lavage ainsi qu'une résistance à la dégradation solaire.
