Description
AN AGROCHEMICAL COMPOSITION
FIELD OF THE INVENTION
The présent invention relates to an agrochemical composition for improving the effectiveness 5 of an herbicide. The présent invention more particularly relates to an agrochemical composition for improving the effectiveness of an herbicide using non-ionic surfactants and electrolytes.
BACKGROUND OF THE INVENTION
Weeds are among the crop pests and they reduce crop économie yield by 10 to 15% yearly, according to the Food and Agriculture Organization of the United Nations. Mean while, weeds are also the hosts of various crop pests and pathogens. Herbicides with different sites of action are by far the most effective weed control tools developed, killing 90 to 99% of the weeds targeted. Undesirable végétation, which inhibits crop growth, is a constantly recuning problem in agriculture. To solvc this problem, researchers arc trying to produce an extensive variety of Chemicals and Chemical formulations effective in the control of such undesirable growth. Modem herbicides, widely classified as pre- and post-emergent herbicides hâve been used in the world, with significant contributions to an increased crop yield and food quality. While pre-emergent herbicides work to prevent weeds from ever growing, post-emergent herbicides work on weeds that hâve already grown. The foliar application and the application through soil defines the nature of herbicide action.
Leaves are the primary sites of entry for most foliar-applied herbicides. The process that drives herbicide absorption through leaf is simple diffusion followed by pénétration and 25 translocation. When the spray droplet lands on the leaf surface it places a high concentration of the Chemical on the leaf surface. Chemicals move from areas of high concentration to low concentration, thus as soon as the spray droplet contacts the leaf, absorption of the Chemical begins.
To enter the leaf, herbicides must first penetrate lhe waxy cuticle (primary barrier to absorption) or other specialized cells on the leaf surface. The cuticle is a layer of overlapping waxy platelets. The cuticle covers the above ground portion of the plant and prevents water and nutrient losses from the plant. As well as protecting the plant front internai losses, the cuticle also prevents some Chemicals from entering the plant although others may move ihrough with relative ease. The variability in Chemical pénétration is a resuit of the Chemical makeup of the cuticle.
Guard cells around stomates, cells surrounding hairs, and cells overlying veins are also 5 responsible for herbicide absorption. Stomata pénétration is generally more rapid than cuticular pénétration. The stomata are minute pores on the surface of leaves that allow gas exchange between the internai and extemal environment. Stomata opening and closure is regulated by the plant and can be affected by light, heat, wind, Chemicals and other factors. The degree of stomatal entry by an herbicide is dépendent on the number and size of the 10 stomata, whether they are open or closed, and on the surface tension of the herbicide. Larger and more numerous stomata allow faster foliar uptake and closed stomata exclude liquids and gases. Chemicals or sprays with high surface tensions (like water) enter the stomata less rapidly than those with low surface tensions.
Stomatal movements are brought about by changes in the turgor pressure of the guard cells which resuit from fluxes of cations. The principal route of cation entry during stomatal opening appears to be via a cation channel which has selectivity for Li* > Na+ > Cs+ > K+ > Rb+. The ionic responses of stomata and the different monovalent cations supports stomatal opening and hence can be utilized as an entry to the herbicides.
Surfactants are expected to further improve the bioefficacy of herbicides. Surfactants are eithcr mixcd within the formulation of hcrbicidally active ingrédient or supplied separateiy as an adjuvant to be sprayed along with the formulation. Surfactants may also be applied as tank mix partner or sprayed before herbicide application as wetting/ sticking agent. Surfactants 25 are included within the formulation due to various purposes e.g. it may altcr the physical characteristics of the spray solution by acting as compatibility agents, buffering agents, antifoam agents, spreading agent, sticking agents and drift control agents. Sometimes, they enhancc postemergence herbicide performance b y incrcasing herbicide absorption into plant tissue, provides rain fastness, decreases photodegradation of the herbicide. Surfactants 30 primarily reduces the surface tension between the spray droplet and the leaf surface.
Surfactants are broadly classified as non-ionic, anionîc, cationic, and amphotcric surfactants.
For the reasons given, there is a need for an agrochemical solution which permit the quick entry of herbicides in the plant for the desired action by developing a stable composition, these compositions being highly active and promoting an increase in the uptake of systemic active ingrédients, and allowing combinability with surfactants and electrolyte ingrédients, and having the propertîes that are advantageous from an applications standpoint, such as, for example, good storage stability and uniform and high biological activity. It would therefore be idéal to use non-ionic surfactants along with electrolytes in order to enhance stomatai pénétration.

Accordingly, it is a primary object of the présent invention to provide an agrochemical composition having enhanced herbicidal action.
Another object of the présent invention is to provide an agrochemical composition comprising herbicide, non-ionic surfactant and electrolyte, said composition has an enhanced herbicidal action.

DETAILED DESCRIPTION OF THE INVENTION
Inventors of the présent invention surprisingly found that co-application of an electrolyte and non-ionic surfactant with at least one herbicide results in fast and better and in some cases long-lasting control of undesirable plant growth. Inventors of the présent invention surprisingly observed that upon foliar application of an agrochemical composition of the présent invention, the electrolyte dissociâtes into free ions and; non-ionic surfactants facilitate passage of free ions through root and shoot transport System. This in-lum results into higher concentration of free ions in the stomatal cell’s intrinsîc environment. The higher concentration of free ions triggers opening of stomata. The opened stomata facilitate efficient uptake of herbicide from leaves surface. This leads to more effective and fast control of undesirable végétation as compared to the compositions without electrolyte and non-ionic surfactant combinations.
The présent invention results into an agrochemical composition which is herbicidally 10 effective due to enhanced uptake of herbicide through stomatal opening.
The combination of electrolyte and non-ionic surfactants in the présent invention enhances herbicidal effect through open stomata and leads to more quick and effective control of undesirable végétation.

Treatment details: This study was performed on grape vineyards at Nashik, Maharashtra, India where the vineyards were predominantly covered by weed plants such as amaranthus viridis, euphorbia hypericifolia, dinebra sp and euphorbia microphylla. The study was întended to evaluate the efficiency of an agrochemical composition according to the présent invention and to understand the rôle of electrolyte and non-ionic surfactant in the herbicidal composition.
Two compositions (Example-12 and Example-20) of 150g/L Gf-ammonium were tested 5 against selected weeds. Weed plants were evaluated on 14* day after treatment (Table 2 and
Figure 2), at which time-point, significantly more burn down effect was observed in régions treated with an agrochemical composition of Example-12 comprisîng both electrolyte and non-ionic surfactant in comparison to an agrochemical composition of Example-21 in which electrolyte was not présent. Composition of Example-20 showed 82.5% control of 10 amaranthus viridis, 85% control of euphorbia hypericifolia, 82.5% control of dinebra spp., and 77.5% control of euphorbia microphylla wherein, composition of Example-12 found better in ail the selected weeds by controlling around 87.5% control of amaranthus viridis., 90% control of euphorbia hypericifolia., 87.5% control of dinebra spp. and 87.5% control of euphorbia microphylla.

Compositions | Percent weed control at 12 DAT | |||
Amaranthus viridis | Euphorbia hypericifolia | Dinebra spp | Euphorbia microphylla | |
Example 12 | 87.50 | 90.00 | 87.50 | 87.50 |
Example 20 | 82.50 | 85.00 | 82.50 | 77.50 |
Evaluation of the effect after two weeks revealed that the green parts of the weed plants had died and therefore that control of the weed plants was effective. Therefore, it was concluded 20 that the agrochemical composition for improving the effectiveness of an herbicide comprisîng electrolyte and non-ionic surfactant showed far more superior effect on commonly found weeds of non-crop lands as well as crop lands viz grasses, commelina spc., cyprus spc., triantham spc., amaranthus viridis, euphorbia hypericifolia, dinebra spp., and euphorbia microphylla weeds than when treated with the compositions without electrolyte and non-ionic 25 surfactant or with the compositions having either of electrolyte or non-ionic surfactant.
The agrochemical composition for improving the effectiveness of an herbicide developed according to the présent invention resulted into an efficacîous composition. The combination of non-ionic surfactant and an electrolyte succès sfully improved absorption and uptake of herbicide which resulted into an increased efficacy. The careful sélection of the non-ionic surfactant and electrolyte in formulating an agrochemical composition provided excellent efficacy onto crops. It is to be understood that the invention is not to be limited to the details of the above embodiments, which are described by way of example only. Many variations are possible.
