NOVELTY - Controlling pests and/or increasing the plant health of a cultivated plant as compared to the respective control, involves application of a pesticide to a plant with at least one modification, parts of such plant, plant propagation material, or at its locus of growth.    USE - For controlling pests and increasing the plant health of a cultivated plant including transgenic plant and modified plant, as compared to the respective control, where increased plant health is to be understood as an increase, compared to the respective control, in a trait selected from yield, plant vigor, early vigor, greening effect, quality, tolerance to environmental stress, herbicide tolerance, insect resistance, fungal resistance or viral resistance or bacterial resistance, antibiotic resistance, content of fine chemicals advantageous for applications in the field of the food and/or feed industry, the cosmetics industry or the pharmaceutical industry, nutrient use efficiency, nutrient use uptake, fiber quality, color and male sterility; and/or increased plant health is to be understood as an alteration or modification, compared to the respective control, in a trait selected from maturation, fertility restoration and color; and for the production of an agricultural product (all claimed); where the transgenic plant and modified plant are selected from cereals, such as maize (corn), wheat, barley sorghum, rice, rye, millet, apples, banana, beet, cabbage, carrot, cauliflower, cherries, citrus fruits, cotton, kiwi, papaya, peanut, pineapple, potato, soybean, sugar-cane, sunflower, walnut, Aceraceae, Apiaceae, Asteraceae, Carifolaceae, Anacardium occidentale, Calendula officinalis, Carthamus tinctorius, Helianthus annus, Brassica sinapioides.    ADVANTAGE - The method provides cultivated plants which show at least one property selected from herbicide tolerance, insect resistance, fungal resistance or viral resistance or bacterial resistance, stress tolerance, maturation alteration, content modification of chemicals present in the cultivated plant, modified nutrient uptake, antibiotic resistance and male sterility compared to the corresponding control plant respectively. The use of pesticide e.g. atrazine and bentazone, in cultivated plants displays a synergistic effect between the trait of the cultivated plant and the applied pesticide; and results in an increased plant health effect in such cultivated plants compared to the plant health effects that are possible with the pesticide, if applied on the non-cultivated plant.    DETAILED DESCRIPTION - Controlling pests and/or increasing the plant health of a cultivated plant as compared to the respective control, involves: application of a pesticide to a plant with at least one modification, parts of such plant, plant propagation material, or at its locus of growth, where the pesticide is selected from atrazine, bentazone, bromoxynil, chloridazon, cyanazine, diuron, hexazinone, isoproturon, metamitron, phenmedipham, pyrazon, terbuthylazine, ametryne, amicarbazone, bromacil, bromofenoxim, desmedipham, desmetryne, dimethametryne, ioxynil, lenacil, metribuzin, pentanochlor, propanil, prometon, prometryne, propazine, pyridate, pyridafol, simazine, simetryne, terbumeton, terbacil, terbutryne, trietazine, chlorobromuron, chlorotoluron, chloroxuron, dimefuron, ethidimuron, fenuron, fluometuron, isouron, linuron, methabenzthiazuron, metobromuron, metoxuron, monolinuron, neburon, siduron and tebuthiuron. INDEPENDENT CLAIMS are included for the following:    (1) seed of a cultivated plant with at least one property selected from herbicide tolerance, insect resistance, fungal resistance, viral resistance, bacterial resistance, stress tolerance, maturation alteration, and content modification of chemicals present in the cultivated plant, modified nutrient uptake, antibiotic resistance and male sterility, which is treated with a pesticide;    (2) a composition comprising the pesticide and a cultivated plant, its parts or cells; and    (3) production of an agricultural product involving application of the pesticide to a cultivated plant with at least one modification, parts of such plant, plant propagation materials, or to its locus of growth, and producing the agricultural product from the plant or parts of such plant or plant propagation material.
