The present invention refers to a plant growth and development, inductive resistance bio-stimulant formulation for phytopathogen virus disease control and its method of preparation from plant extracts and other natural origin products. The plant growth and development, inductive resistance bio-stimulant formulation for phytopathogen virus disease control is composed of plant extracts and vegetable oils proceeding from Chihuahua semi-desert plant varieties and absolute oils and aromatic plant extracts, and other components. This formulation has been widely proven in field and is useful for phytopathogen virus disease control, preventing and reducing DNA and RNA virus damage of greater impact in vegetable and fruit crop production, ameliorating the number of damaged plants, delaying the appearance of virosis symptoms, significantly decreasing the severity of damage, reducing virus dissemination in plantation, favoring growth continuity in plant and assuring a greater yield under attack conditions.

Disclosed herein are methods of controlling undesirable vegetation in pineapple, which comprise applying to vegetation or an area adjacent the vegetation or applying to soil to prevent the emergence or growth of vegetation (a) penoxsulam or an agriculturally acceptable salt thereof. The methods can further comprise applying (b) a second pesticide or an agriculturally acceptable salt or ester thereof to the vegetation or the area adjacent the vegetation or to the soil adjacent thereto. In some embodiments, (b) includes an ACCase inhibitor such as cyhalofop-butyl, haloxyfop-P-methyl, fluazifop-P-butyl, or combinations thereof.

Disclosed herein includes a safening composition comprising an herbicidally effective amount of (a) at least one phenoxy herbicide, or an agriculturally acceptable salts, esters, and amides thereof; (b) at least one safener from quinolinyloxyacetate family of chemicals, or agriculturally acceptable salts, esters and amides thereof, wherein the weight ratio of the at least one phenoxy herbicide to cloquintocet is from about 500:1 to about 1:1. Herbicidal injury caused by a phenoxy herbicide in wheat and barley is reduced with the use of low rates of cloquintocet.
