Abstract

In a package containing two concentrated, incompatible crop protection agents at least one of which is a liquid (20) formulated for dilution by water, a container (10) contains a major amount of a first formulation of a said liquid agent and a minor amount of a second formulation of a different said agent in the form of at least one water disintegrable capsule or tablet of a size suitable for fitting in the cap or passing through the neck of the container, the formulations being separated by a membrane impermeable to liquid in either formulation. <IMAGE>

Description

SPECIFICATION Twin-packs for use in agriculture This invention relates to twin-packs for use in agriculture. Progress in crop protection research is leading to the production of ever more active agents.
In former years application rates of pesticides were commonly measured in kilograms per hectare; today, several agents are known which are effective at rates of the order of 10-100 grams per hectare.
Increasingly also, pesticides are applied in admixture. This is desirable for several reasons. Thus to save labour, insecticides and fungicides (say) may be applied to a crop simultaneously. Or two highly selective agents, eg. herbicides, may be applied to soil or crops to combat two different types of weeds.
Problems of incompatibility may arise when pesticides are being formulated in concentrated form for application simultaneously at two very different rates. We have devised a twin-pack for concentrated pesticides which conveniently overcomes such problems, and is easily and safely diluted to spraying strength by the farmer, simply by adding the contents of the pack to water in his spray tank reservoir.
Accordingly to the present invention, we provide a package for two concentrated incompatible crop protection agents formulated for dilution by ater, at least one of which includes a liquid phase, said package comprising a container having a neck leading to a mouth, with a removable cap for the mouth, and containing a major amount of a first formulation of a crop protection agent and a minor amount of a second formulation of a different crop protection agent, the second formulation being in the form of a water-disintegrable tablet or capsule of dimensions enabling it to fit in the cap or pass through the neck of the container, the second agent being separated from the first by a membrane impermeable to liquid in either formulation. Preferably the first crop protection agent is formulated as a liquid.
By the term 'crop protection agent' we include insecticides, herbicides, fungicides, plant growth regulators and like materials that are applied to pests, growing crops or the soil in which crops grow.
The agents may be of the same type, eg. two different herbicides, or of different types, eg. an insecticide and a fungicide. The package may, if desired, contain more than two different agents.
Thus two compatible agents may be mixed in the first formulation; or two compatible agents may be mixed in the tablet or capsule. The package may contain more than one tablet or capsule (eg. two or ten tablets or capsules). When the capsules are of the same kind, this is a convenient way of increasing the application rate of the minor component.
Specific embodiments of the invention will now be described with reference to the drawings, in which Figure 1 is a vertical section through a first container according to the invention.
Figure 2 is a vertical section through a second container according to the invention.
The container of Figure 1 comprises a body 10 of blow-moulded plastic having a capacity of one litre and provided with an externally threaded neck 11 terminating in a mouth 12. The container is filled to the level of neck 11 with a formulation 20 of the herbicide ioxynil (350g active ingredient), as the octanoate ester with surfactants in petroleum solvent. The mouth 12 of the container is sealed with a metal foil 13. On top of foil 13 rests an effervescent tablet 14 containing 10g of the herbicide DPX 4189 (chlorsulfuron). The tablet is coloured deep green (for safety reasons, to distinguish it from effervescent tablets commonly used as drugs) and contains a mixture of a bicarbonate salt and citric acid so that it breaks up rapidly in contact with water. The tablet 14 is accommodated in a recess 15 of a threaded cap 16 which fits over the mouth 12 and neck 11 of container 10.For extra security in transit and storage, the cap 16 is held in place by a shrinkable band 17 of plastics material. The contents of the package 10 are sufficient to treat one hectare. For use, the farmer breaks the band 17, removes cap 16 and places tablet 14 in the water in his sprayer reservoir.
He then breaks foil 13 and pour the liquid contents 20 into the reservoir. After thorough mixing, spraying is carried out in the usual way.
A second embodiment of the invention is illustrated in Figure 2. The body 10, neck 11 and mouth 12 of the container are of the same structure as before, and again the container is filled to the neck by the same formulation 20 of ioxynH herbicide shown in Figure 1. However, in this embodiment the herbicide chlorsulfuron (1 0g) is provided in the form of water-dispersible grains 18 disposed in a capsule 19 of water-soluble polyvinylpyrollidone. The density of the capsule 19 is controlled so that it floats in formulation 20. The cap 21 has its inner surface 22 flush with mouth 12, and is secured by shrinkable band 17 as before.
In use, the farmer cuts band 17 as before, unscrews cap 21 and pours the entire contents of the container into water in his sprayer reservoir, being careful to ensure that the capsule 19 is not left behind in the container. Stirring causes the capsule 19 to dissolve, and its contents 18 to be uniformly dispersed through the water together with formulation 20 - spraying can then follow as before.
