Description

PESTICIDAL COMPOSITIONS
The present invention relates to novel compositions, their preparation, formulations containing them and to their use for the control of insect pests.
Insecticides have been increasingly used in agriculture over the past thirty years to control insect pests, thereby increasing the yield per acre that land under cultivation can provide. However, with increasing use of a particular insecticide, the insect population modifies its susceptibility to the insecticide and resistance to that insecticide may occur. Thus, by 1980, resistance to the organochlorine and organophosphorous insecticides was common and, by 1988, resistance to the pyrethroids in certain insect species was becoming widespread. Thus, for example, pyrethroid resistance in heliothis species in Australia, Thailand, Turkey and the Americas is becoming a major problem in the cotton growing industry in these countries.
There are a number of ways of countering increasing resistance of insect species to insecticides. One way is to develop new series of insecticides which have a different mode of action to existing insecticides and are not cross-resistant with these. However, this is time-consuming and expensive and there is no guarantee of success. A further possibility is to increase the activity of existing series of insecticides so that resistant insects become susceptible to the insecticides. This can be done by developing more active analogues of existing insecticides or by increasing the activity of existing insecticides by combining them with a substance which increases their activity (a "potentiator") or formulating them in a manner which enables them to overcome or by-pass the insects' resistance mechanism.
Piperonyl butoxide is a potentiator that has been commonly used to potentiate the activity of the pyrethrins and the pyrethroids against susceptible and resistant insect species. Piperonyl butoxide (5-[2-(2-butoxyethoxy)ethoxymethyl]-6-propyl-l,3-benxodioxole) acts by inhibiting enzymes, mixed function oxidases, which are present in susceptible and more so in pyrethrin/pyrethroid and some carbamate resistant insects and degrades these insecticides.
n-Propyl- allate is an antioxidant that is commonly used in the food industry as a preservative. It has also been used in insecticide formulations, for example, Hungarian Patent Application No 34100 discloses insecticidal compositions containing inter alia permethrin, piperonyl butoxide and an antioxidant such as n-propyl gallate. We have discovered that BHT and BHA can potentiate the activity of insecticides, such as the pyrethrins, the pyrethroids and the organophosphorus series of insecticides, against susceptible and resistant insect species including Musca domestica and heliothis spp. In addition, we have found that the potentiating effect of piperonyl butoxide appears to be adversely effected by light, i.e. piperonyl butoxide is photosensitive; the addition of gallic acid esters to piperonyl butoxide protects piperonyl butoxide against light induced degradation.
Accordingly, in a first aspect, the present invention provides a composition which comprises piperonyl butoxide a gallic acid ester in a ratio of 3:1 to 1:10 by weight. Suitable gallic acid esters include alkyl esters, most suitably those formed from straight chain alkyl esters where the alkyl substituent contains up to 12 carbon atoms, in particular propyl, octyl and dodecyl gallate esters. Preferably the gallic acid ester is n-propyl gallate.
In a further aspect, the present invention provides an insecticidal composition which comprises an insecticide, piperonyl butoxide and n-propyl gallate, wherein piperonyl butoxide and n-propyl gallate are in a ratio of 3:1 to 1:10 by weight, suitably in a ratio of 2.5:1 to 1:7 and are preferably in a ratio of 2:1 to 1:5 by weight.

The formulation for agrochemical use which comprises n-propyl gallate and piperonyl butoxide and/or one or more insecticides from the organophosphorous, pyrethroid, pyrethrin or lipid amide classes of insecticides may contain a suitable carrier. The carrier may be liquid, solid or gaseous or comprise a mixture of such substances, and the composition of the present invention may be present in a concentration of from 0.025 to 99% w/v depending upon whether the formulation requires further dilution.
Dusts, powders and granules and other solid formulations comprise the compositions of the present invention in intimate admixture with a powdered solid inert carrier for example suitable clays, kaolin, bentonite, attapulgite, absorbent carbon black, talc, mica, chalk, gypsum, tricalcium phosphate, powdered cork, magnesium siliate, vegetable carriers, starch and diatomaceous earths. Such solid formulations are generally prepared by impregnating the solid diluents with solutions of the combinations of the present invention in volatile solvents, evaporating the solvents and, if desired grinding the products so as to obtain powders and, if desired, granulating, compacting or encapsulating the products.
Sprays of the compositions of the present invention may comprise a solution in an organic solvent (e.g. those listed below) or an emulsion in water (dip wash or spray wash) prepared in the field from an emulsifiable concentrate (otherwise known as a water miscible oil) which may also be used for dipping purposes. The concentrate preferably comprises a mixture of the active ingredients, with or without an organic solvent and one or more emulsifiers. Solvents may be present within wide limits but preferably in an amount of from 0 to 90% w/v of the composition and may be selected from kerosene, ketones, alcohols, xylene, aromatic naphtha, and other solvents known in the formulating art. The concentration of emulsifiers may be varied within wide limits but is preferably in the range of 5 to 25% w/v and the emulsifiers are conveniently non-ionic surface active agents including polyoxyalkylene esters of alkyl phenols and polyoxyethylene derivatives of hexitol anhydrides and anionic surface active agents including Na lauryl sulphate, fatty alcohol ether sulphates, Na and Ca salts of alkyl aryl sulphonates and alkyl sulphosuccinates, soaps, leuthrins, hydrolysed glues, etc. Cationic emulsifiers include benzalkonium chloride and quaternary ammonium ethosulphates.

Emulsifiable concentrates comprise emulsifying agents, and often an organic solvent, such as kerosene, ketones, alcohols, xylenes, aromatic naphtha, and other solvents known in the art.
Wettable powders and emulsifiable concentrates will normally contain from 5 to 95% by weight of the active ingredient, and are diluted, for example with water, before use.
Aqueous suspensions of a compound of Formula (I) may comprise a suspension in water together with suspending, stabilising or other agents. The suspensions or solution may be applied per se or in a diluted form in known fashion.
Aerosol sprays may be prepared as a simple solution or suspension of the active ingredient in the aerosol propellant and co-solvent such as halogenated alkanes and the solvents referred to above, respectively. Pour-on formulations may be made as a solution or suspension of a combination of the present invention in a liquid medium. Suitably-moulded, shaped plastics articles impregnated with a combination of the present invention including impregnated collars, tags, bands, sheets and strips are also useful formulations. Suitably the plastics material is a polyvinyl chloride (PVC) .
The composition of the present invention may be used to control insect and acarine pests.
Thus the present invention provides a method for the control of arthropods and which comprises administering to the arthropod or to its environment an arthropodically effective amount of an insecticidal composition of the present invention. The present invention also provides a method for the control and/or eradication of arthropod infestations of animals and/or of plants, (including trees), and/or stored products which comprises administering to the animal or locus an effective amount of an insecticidal composition of the present invention. The present invention further provides for the insecticidal compositions of the present invention for use in human and veterinary medicine, in public health control and in agriculture for the control of arthropod and/or helminth pests.
The insecticidal compositions of the present invention are of particular value in the protection of field, forage, plantation, glasshouse, orchard and vineyard crops, of ornamentals and of plantation and forest trees, for example, cereals (such as maize, wheat, rice, sorghum), cotton, tobacco, vegetables and salads (such as beans, cole crops, curcurbits, lettuce, onions, tomatoes and peppers), field crops (such as potato, sugar beet, ground nuts, soyabean, oil seed rape), sugar cane, grassland and forage (such as maize, sorghum, lucerne), plantations (such as of tea, coffee, cocoa, banana, oil palm, coconut, rubber, spices), orchards and groves (such as of stone and pip fruit, citrus, kiwifruit, avocado, mango, olives and walnuts), vineyards, ornamental plants, flowers and shrubs under glass and in gardens and parks, forest trees (both deciduous and evergreen) in forests, plantations and nurseries.
They are also valuable in the protection of timber (standing, felled, converted, stored or structural) from attack by sawflies (e.g. Urocerus) or beetles (e.g. scolytids, platypodids, lyctids, bostrychids, cerambycids, anobiids) .
They have applications in the protection of stored products such as grains, fruits, nuts, spices and tobacco, whether whole, milled or compounded into products, from moth, beetle and mite attack. Also protected are stored animal products such as skins, hair, wool and feathers in natural or converted form (e.g. as carpets or textiles) from moth and beetle attack; also stored meat and fish from beetle, mite and fly attack.
The insecticidal compositions of the present invention are thus useful in the control of arthropods e.g. insects and acarines in any environment where these constitute pests, e.g. in agriculture, in animal husbandry, in public health control and in domestic situations.
