Biodiesel Solvents in Pesticide Compositions
Disclosed are pesticide compositions that utilize biodiesel as a solvent. The disclosed compositions may be utilized for controlling pests, such as nematodes and weeds, and for enhancing growth of plants.
1 . A pesticide composition comprising:
(a) an effective amount of a pesticide for controlling a pest;
(b) biodiesel; and
(c) an effective amount of a nitrogen source;
wherein the composition has a molar ratio of total carbon to total nitrogen (C:N) of about (22.4-5.6):1.
2 . The composition of claim 1 , wherein the pesticide is a nematicide.
3 . The composition of claim 2 , wherein the nematicide is effective for controlling a nematode selected from a group consisting of Rotylenchulus reniformis, Dorylaimida spp., Meloidogyne incognita, Hoploaimus galeatus, Paratrichodorus minor , and combinations thereof.
4 . The composition of claim 1 , wherein the composition is effective for reducing nematodes by at least about 50% when applied at an application rate of about 1 ml/kg soil.
5 . The composition of claim 1 , wherein the composition does not reduce microbivorous nematodes by more than about 50% when applied at an application rate of about 1 ml/kg soil.
6 . The composition of claim 1 , wherein the pesticide is an herbicide.
7 . The composition of claim 6 , wherein the herbicide is effective for controlling a weed selected from a group consisting of Ipomoea spp., Digitaria sanguinalis, Senna obtusifolia, Datura stramonium, Setaria glauca, Amaranthus retroflexus , and combinations thereof.
8 . The composition of claim 6 , wherein the composition is effective for reducing weeds by at least about 50% when applied at an application rate of about 1 ml/kg soil.
9 . The composition of claim 1 , wherein the pesticide is a fungicide.
10 . The composition of claim 9 , wherein the fungicide is effective for controlling a fungus selected from a group consisting of Rhizoctonia solani. Pythium spp., and Fusarium spp. and a combination thereof.
11 . The composition of claim 1 , wherein the pesticide is selected from a group consisting of a menthol compound, an alkyl cyanamide compound, a 3,5-alkyltetrahydro-1,3,5-thiadiazine-2-thione compound, an aldehyde compound comprising a cyclic aromatic substituent, an isothiocyanate compound, a capsaicinoid compound, an unsaturated aldehyde compound, a phenol compound optionally substituted with alkyl, a halogenated propene, a diazarine compound, an orange terpene, and combinations thereof.
12 . The composition of claim 1 , wherein the nitrogen source is an organic nitrogen source.
13 . The composition of claim 12 , wherein the organic nitrogen source comprises urea, casein, or both.
14 . A pesticide composition comprising:
(a) biodiesel;
(b) an effective amount of a pesticide for controlling a pest; the pesticide selected from a group consisting of a menthol compound, an alkyl cyanamide compound, a 3,5-alkyltetrahydro-1,3,5-thiadiazine-2-thione compound, an aldehyde compound comprising a cyclic aromatic substituent, an isothiocyanate compound, a capsaicinoid compound, an unsaturated aldehyde compound, a phenol compound optionally substituted with alkyl, a halogenated propene, and combinations thereof.
15 . A method for preparing a pesticide composition, the method comprising combining:
(a) an effective amount of a pesticide for controlling a pest;
(b) biodiesel; and
(c) an effective amount of an nitrogen source;
wherein the composition has a molar ratio of total carbon to total nitrogen (C:N) of about (22.4-5.6):1.
16 . A method for controlling soil-bourne pests and weeds comprising applying a liquid soil-amendment composition at an application rate of at least about 1 ml/kg soil, the soil-amendment composition comprising:
(a) an effective amount of a pesticide for controlling a pest; and
(b) biodiesel.
17 . The method of claim 16 , wherein the composition further comprises
(c) an effective amount of an nitrogen source;
wherein the composition has a molar ratio of total carbon to total nitrogen (C:N) of about (22.4-5.6):1.
18 . The method of claim 16 , further comprising applying another separate soil amendment composition comprising an effective amount of a nitrogen source in order to achieve a molar ratio of total carbon to total nitrogen (C:N) of about (22.4-5.6):1 in the soil to which the amendment compositions are applied.
