MXPA06009888A - Crop oil concentrate adjuvants containing amine surfactants - Google Patents

Abstract

In agricultural practice it is known to use emulsifiable oils (commonly referred to a Crop Oil Concentrates, COC ) as bioefficacy enhancers for pesticides, especially herbicides. Cationic surfactants are widely known to be particularly effective bio-active enhancers for herbicides, especially for glyphosate-type herbicides. The present invention includes two novel aspects:1) While the vast majority of COCs are petroleum-based paraffinic oils or esterified seed oils, this invention embodies a new oil phase, a hydrocarbon oil such exemplified by EXXON-MOBIL'S D-130, which when combined with the surfactants described herein, exhibits surprising enhancement of herbicidal activity in field tests;and 2) COC's are designed to form stable emulsions in water. The combination of cationic surfactants and phosphate esters in this invention not only form very stable emulsions in water, but, surprisingly, also form extremely stable emulsions in concentrated liquid fertilizers, including 32-0-0 fertilizer.

Agricultural adjuvants Adjuvants are chemical materials that are often used as a component of a formulation containing one or more 'agriculturally active materials, and which are designed to perform specific functions, including wetting, spraying, adhering, reducing evaporation, reducing the volatility, regulation, emulsification, dispersion, reduction of the sprinkler bypass, and reduced foaming. ' No single adjuvant can perform all of these functions, but often different compatible adjuvants can be combined to perform multiple functions simultaneously; therefore, adjuvants are a diverse group of chemical materials. Within the meaning of the term "Adjuvants" is included any substance added to the spray tank to modify the performance of a pesticide, the physical properties of the spray mixture, or both.

'Spray application is perhaps the weakest link in the chain of events that a pesticide follows through its development procedure. Some researchers claim that up to 70 percent of the effectiveness of a pesticide depends on the effectiveness of the application of the spray. The selection of a suitable adjuvant can reduce or even eliminate the problems of spray application associated with stability, solubility, incompatibility, suspension, foaming, bypass, evaporation, volatility, degradation, adhesion, penetration, surface tension and pesticide coverage, thus improving the overall efficiency and effectiveness of the pesticide.

Adjuvants surface agents physically alter the surface tension of a spray droplet. For a pesticide to perform its function correctly, a drop of spray must be able to wet the foliage and spread evenly on a leaf. Surface agents enlarge the area of coverage of the pesticide, thereby increasing the 'exposure of the pest to the chemical. Without proper wetting and spreading, spray droplets often slip or fail to adequately cover these surfaces. These materials improve the properties of absorbency, emulsification, dispersion, extensibility, adhesion, wetting or penetration of pesticides. Surface agents are most often used with herbicides, to help the pesticide to spread above, and to penetrate the waxy outer layer of a leaf, or to penetrate through the small hairs on the surface of the sheet.

Although surface agents can be anionic, cationic or non-ionic, nonionic surface agents are the most commonly used. The "non-ionic" multi-purpose surface agents are composed of alcohols and fatty acids, have no electrical charge and are compatible with most pesticides. Some other surface agents can be cationic (charge +) or anionic (charge -) and are specialized adjuvants that are used in certain situations and with certain products. Anionic surface agents are used mostly with acids or salts, and are more specialized and used as dispersants and compatibility agents. - Cationic surface agents are used less frequently but one group, the ethoxylated fatty amines, is sometimes used with glyphosate. herbicide.

Silicone-based surface agents are increasing in popularity due to their superior extensibility. Some of the surface agents are mixtures of non-ionic surface agents (NIS) and "silicone, while others are totally silicone." The combination of a NIS and a silicone surface agent can increase the absorption in a plant, so that the time between the two can be shortened. application and rains There are generally two types of silicone organ surface agents: polyether silicones that are soluble in water and alkyl silicones that are soluble in oil, unlike the types of polyether silicone, alkyl silicone surface agents work well with oil-based sprays, such as latent and summer oil sprays used in insect control. Improved alkyl silicone oil sprays can maximize insecticidal activity and still allow for the use of significantly lower proportions of pesticide, which reduce crop residue levels.

The adhesion adjuvants increase the adhesion of the solid particles to the target surfaces. These adjuvants can decrease the amount of pesticide that is washed away during irrigation or rain. The adherents. they can also reduce the evaporation of the pesticide and achieve some slow ultraviolet (UV) degradation of the pesticides. Many adjuvants are formulated as extensors-adherents to make a general purpose product that includes a wetting agent and an adhesive.

The function of the extender adjuvants, such as the adhesion surface agents, is to hold pesticides for longer in the target area, slowing down volatilization and inhibiting UV degradation.

The surface agents that penetrate the plants have a molecular configuration that improves the penetration in the plants of some pesticides. A surface agent of this type can increase the penetration of a pesticide in one species of plant, but not in another. Systemic herbicides, auxin type herbicides, and some displaceable fungicides may have their activity increased as a result of improved penetration.

The adjuvant compatibility agents are. Especially useful when pesticides are combined with liquid fertilizers or other pesticides, particularly when the combinations are physically or chemically incompatible, such as in the cases in which in the spray tank - lumps or uneven distribution occur. A compatibility agent can eliminate the problems associated with those situations.

Regulatory or pH-modifying adjuvants are generally employed - to prevent the problems associated with alkaline hydrolysis of pesticides, which are found when the pH of a pesticide exceeds about 7.0, by stabilizing the pH at a relatively constant level. Extreme levels of pH in the spray mixture can cause some pesticides to decompose prematurely. This is particularly true for organophosphate insecticides, but some herbicides can decompose into inactive compounds in a matter of hours or minutes in alkaline situations (pH > 7). For example, the Cygon insecticide (dimethoate) loses 50 percent of its pest control power in just 48 minutes when mixed in pH 9 water. However, at a pH of 6 it takes 12 hours for the degradation progress to that point. On the other hand, sulfonyl urea (SU) herbicides tend to decompose more rapidly when the pH is below 7. At low pHs, 1 herbicide 2,4-D is an uncharged molecule. At higher pH, 2,4-D tends to become more anionic or negatively charged, which can affect its movement in the environment. Leaf covers often have a high pH which contributes to poor performance with certain herbicides. -The use of a regulating or acidifying adjuvant can stabilize or lower the pH of a spray solution, thereby improving the stability of the pesticide being used.

Mineral control adjuvants are used to mask the problems associated with water hardness minerals in the spray water, which can decrease the effectiveness of many pesticides. Mineral ions such as calcium, magnesium, salts and carbonates, are commonly found in -. the hard water. These ions can agglutinate with the active ingredients of some pesticides, especially salt-formulated herbicides, such as Roundup ™ (glyphosate). Poast ™ (sethoxydim), - Pursuit ™ (imacetapir), and Liberty ™ (glufosinate), resulting in poor weed control. The use of water conditioning adjuvants gives the hard water minerals something to agglutinate with, other than the herbicide. In addition, some adjuvants based on ammonium sulfate can be used to divert hard water problems.

The retarding derivative adjuvants improve the placement in the meta of the sprinkler. insecticide to increase, the average size of the drop, since the derivation is a function of the size of the drop, with drops of diameters of 100 microns or smaller, which tend to drift away from the target areas.

. The adjuvants of defoaming agents are used to control the. foam or foamed head often present in some spray tanks, which is a result of the surface agent used and the type of spray tank agitation system, which can often be reduced or eliminated by adding a small amount of spray inhibitor. the foam.

The thickening adjuvants increase the viscosity of the spray mixtures, which provides control over bypass or slow evaporation after the spray has been deposited in the target areas.

Oil-based adjuvants have been gaining popularity especially for the control of oily weeds. There are three types of oil-based adjuvants: crop oils, crop oil concentrates (COC) and vegetable oils. The culture oil adjuvants are derived from paraffin-based petroleum oil. The cultivation oils are generally 95-98%. of - oil with 1 to 2% surface agent / emulsifier. The cultivation oils promote the penetration of an insecticide spray either through the waxy cuticle of the plant or through the chitinous shell of the insects. Culture oils may also be important to help solubilize less water-soluble herbicides, such as Poast ™ (sethoxydim), Fusilade ™ (fluacipropo-butyl) and atrazine. Traditional crop oils are more commonly used in the control of insects and diseases than with herbicides. Concentrates of culture oil (COC) are a mixture of cultivation oils (80-85%) and nonionic surface agents (15-20%). The purpose of the non-ionic surface agents in this mixture is to emulsify the oil in the spray solution and decrease the surface tension of the general spray solution. Vegetable oils work best when lipophilic characteristics are improved, and a common method of achieving this is through the esterification of common seed oils, such as rape seed, kidney bean. soybeans and cotton. Methylated seed oils (MSO) are comparable in performance with crop oil concentrates in that they increase the penetration of the - pesticide In addition, silicone-based MSOs are also available that take advantage of the silicone extension capacity and the penetration characteristics of the MSO's.

Special purpose or utility adjuvants are used to bypass or correct certain conditions associated with mixing and application, such as impurities in the spray solution, extreme pH levels, bypass, and compatibility problems between pesticides and liquid fertilizers. . These adjuvants include acidifiers, regulating agents, water conditioners, antifoaming agents, compatibility agents, and derivatization control agents.

Fertilizer-based adjuvants, particularly nitrogen-based fertilizers, have often been added to spray solutions to increase their herbicidal activity. Research has shown that the addition of ammonium sulfate to spray mixtures increases herbicidal activity in numerous hard-to-kill broadleaf weeds. Fertilizers containing ammonium nitrogen have increased the effectiveness of certain weak acid, polar herbicides such as Accent ™ (nicosulfuron), Banvel ™ (dicamba), Blazer ™ (acifluorfen-sodium), ™ Roundup ™ (glyphosate), - Basagran ™ (bentazon), Poast ™ (sethoxydim), Pursuit ™ (imacetapir), and 2,4-D amine. The previous fertilizer-based adjuvants consisted of dry ammonium sulfate (AM§) (in degree of spray) to 7.72 kg per 0.38 m3 of spray volume (2%). Studies of these adjuvants have shown that the absorption of Roundup ™ was more pronounced when the spray water contained relatively large amounts of certain hard water ions, such as calcium, sodium and magnesium. It is thought that the ions of the fertilizer were bound with the hard water ions, thereby improving the insecticidal action.
