Definitions

  • the present invention relates to pesticides and in particular to a plant pesticide comprising (a) an avermectin and (b) sulphur or a sulphur-containing compound.
  • the invention also relates to uses of these pesticides in the treatment of plant diseases.
  • Thiovit® is a registered product of a Syngenta Group Company and its active constituent is 80% elemental sulphur. It is a micronised sulphur formulation that mixes easily with water to form a spray with good spreading and sticking properties. It is classified as a fungicide/miticide, used for the control of powdery mildew, rust, mites, aphids and thrips in pome and stone fruit, citrus, grapevines, kiwifruit, strawberries and some vegetables.
  • Powdered Mildew This fungal disease produces a fine white coating on the surface of leaves and buds.
  • concentration of Thiovit® recommended to treat this disease ranges between 20g - 40g per 10L of spray. It is recommended that it be applied at intervals between 10 days and 2-3 weeks or as necessary. However, in general practice, the concentrations used are much higher and the rates of applications are much more frequent than those recommended. Because of its low efficacy, Thiovit® is not commonly used by growers to treat powdered mildew. Rusts. There are hundreds of different fungi that cause the disease called rust.
  • Thiovit® recommended to treat this disease ranges between 20g - 40g per 10L and it is recommended that it be applied when the pest or disease is first seen and then repeating as necessary.
  • Mites The group of mites which cause plant damage include the eriophyid mites, such as grape leaf blister mite and citrus bud mite; the tarsonemid mites such as cyclamen mite, the spider mites, and the two— spotted mite. Two-spotted mite known as
  • Aphids These small insects are sometimes referred to as plant lice.
  • the concentration of Thiovit® recommended to treat this disease ranges between 20g - 40g per 10L and it is recommended that plants be treated at intervals between 10 days and 2- 3 weeks or as necessary.
  • Aphids are also commonly treated with broad spectrum systemic pesticides such a Rogor® or Lebaycid®, which are both odorous organophosphates.
  • Thrips These plant pests have a variety of feeding habits. Some thrips feed on leaves only and others on flowers only. Others feed on decaying organic matter such as dead leaves or fungi. Others feed on aphids or mites. Western flower thrips attack a wide range of ornamental plants and many fruit and vegetable crops. These thrips are about 1 mm long and form pale yellow to brownish in colour, like many other thrips. Infected plants show flecking, silvering and deformation of flowers, buds and fruit. Thrips prefer to feed on floral parts, but will also attack young leaves and stems. Treatment for thrips is similar to that for aphids. The most commonly used pesticides are the systemic organophosphates Rogor® and/or Lebaycid®.
  • Sulphur has been used as a contact fungicide and insecticide on plants for at least 2,500 years. More recently agents that release sulphur such as dimethyldithiocarbamic acid have been used.
  • Captafol another organic sulphur-containing compound, has been used as an agricultural fungicide, especially for potatoes.
  • Thiovit® for ornamental and vegetable plants is to spray as soon as pest or disease (Powdery Mildew, Two-spotted Mite, Bean Rust, Tomato Russet Mite, Bean Spider Mite) is first noticed with further applications every 10 to 21 days, or as necessary, at concentrations of 20g-40g/10L.
  • this recommended spraying regime is not effective at all in many cases.
  • resistance to chemicals has evolved in more than 500 species of insects and mites, and 100 species of plant pathogens. The most serious resistance problems have occurred in pests that are frequently treated.
  • resistance to insecticides such as Diazinon®, Talstar® and sulphur formulations is common in exactly those pests (eg. whiteflies, western flower thrips, spider mites and aphids) that cause such serious damage to the plants that they are often sprayed.
  • Some resistant mechanisms are effective against entire classes of chemicals - this is called "cross-resistance" and allows pests to be resistant even to pesticides to which they have never been exposed. Once resistance evolves, it rarely declines enough to allow the pesticide to be used again to any significant extent.
  • Avermectins are a class of highly active broad - spectrum anti-parasitic agents isolated from fermentation broths of Steptomyces avermitilis.
  • the avermectins have anthelmintic and insecticidal activity. Their potency varies with the avermectin and with the organism they are used to treat.
  • Stromectol® containing the ivermectin (22, 23- dihydroavermectin Bla and 22, 23-dihydroavermectin Bib), is indicated in humans for the treatment of onchocerciasis and intestinal strongyloidiasis. It is incompletely absorbed (50% bioavailability) following oral doses of ivermectin tablets.
  • ivermectin It is metabolised in humans, and both ivermectin and its metabolites are excreted almost exclusively in the faeces, with less than 1% of the administered dose being excreted in the urine.
  • the plasma half-life of ivermectin in man is about 12 hours, and that of the metabolites is about 3 days.
  • Parasitic diseases are common in animals and can affect the skin, ears, stomach, intestines, heart, lungs and liver.
  • Ivermectin is used to kill and prevent parasites such as fleas, ticks, mites and worms.
  • An ivermectin commonly used in agriculture is Ivomec® liquid for sheep.
  • This topically applied, systemically active, parasiticide for sheep consists of a 0.08% solution of ivermectin, and is formulated for external application to sheep only.
  • Ivomec® Pour-on for cattle is formulated only for cattle, and consists of a 0.5% solution of ivermectin, a more highly concentrated solution than the one for sheep.
  • the recommended dosage of Ivomec® is 0.5mg ivermectin per kilogram of body weight, with the concentration of ivermectin in Ivomec® Pour-on for cattle being 5mg per ml of solution.
  • Abamectin consists of a mixture of avermectin B ⁇ a and B ⁇ (not the dihydro derivatives mentioned above) obtained through fermentation of Streptomyces avermitilis.
  • Abamectin has been considered a useful chemical for controlling leafininer fly. Since it is derived from a biological source, it is a bio-rational product that can be used in an environmentally friendly manner in pest management programs.
  • Abamectin has been effective against a number of pests, such as mites, ants, cockroaches, and selected pest species of lepidoptera (Lasota and Dybas, 1991), and is considered a selective insecticide with relatively low toxicity to many non-target arthropods.
  • Mujica et al evaluated the effectiveness of abamectin when applied alone or mixed with plant oil on leafminer fly, Liriomyxa huidobrensis Blanchard, on bean plants under laboratory and greenhouse conditions.
  • the addition of plant oil to abamectin sprays to obtain 1% oil spray concentration increased the effectiveness of the insecticide to the extent that the active ingredient of the insecticide could be reduced by one-half to three-fourths of the normal dosage (0.15%).
  • Abamectin normal concentration commercially recommended
  • 0.15% Abamectin concentration with l% plant oil 0.075%) and 0.1125%
  • Chemical pesticides including fungicides, insecticides, and miticides, continue to be heavily relied upon for pest control in agriculture.
  • a composition comprising an avermectin and sulphur has a synergistic effect in controlling pest infestation in a wide variety of agricultural and horticultural species i.e. a composition comprising an avermectin and sulphur was more effective in the control and treatment of plant pest diseases than a composition comprising either avermectin or sulphur alone. Further, it was found that the concentration of the avermectin required for the above-mentioned purpose may be reduced to a surprisingly low level while still achieving synergism.
  • Ivermectin in combination with sulphur can be used as a plant pesticide.
  • Ivermectin was previously known to be useful as an anthelmintic for both veterinary and human purposes and has been used both internally and externally. It has also previously been used to treat sea lice infestation on marine fish. Its application in the agricultural field as a pesticide in combination with sulphur, however, was not previously considered and the benefits of such a combination were therefore not recognised.

  • Agral® and brought to a final volume of 16 L with water.
  • Agral is a standard, well-
  • surfactant used widely by plant growers as a carrier for pesticides. This solution was mixed and shaken vigorously to a homogenous mixture. Agitation and mixing of the solution also continued during the application of the composition to plants.
  • Example 1 The compositions described in Example 1 were applied to several plants.
  • the application of the Thiovit/Ivomec composition is described below.
  • the spraying programme was separated into three treatment stages. The first stage of spraying was regarded as the pre-infection period, and began at 4-5 weeks of plant growth, before infection was noticed. Pre-infection applications were considered to be more effective than post-infection.
  • the objective of the experiments was to have a crop as free from visible signs of pests as possible.
  • the plants were sprayed irrespective of the presence of infection. This was repeated one more time at a 4-day interval. Therefore, the interval between pre-infection applications was 4 days. For example, if the first pre-infection application was made on 01-05-99, the second pre-infection application was made on 05-05-1999.
  • the next stage of spraying was considered the maintenance treatment. This was applied 4-5 weeks after the last pre-infection application, even in the absence of disease. This was repeated one more time if it was considered necessary.
  • the necessity of repeating the maintenance treatment depended on the visual appearance of infection, the visual appearance of plant damage, and climatic changes e.g. wind, rain and humidity.
  • the interval between maintenance treatments was 4-5 weeks.
  • the plants were generally substantially free from visible infection for a period of 7-8 weeks or more.
  • Example 1 the pesticides described in Example 1 were applied without dilution. Spraying was not carried out in very hot weather, in wet or cold frosty weather, or on a windy day; warm days were preferably chosen, where temperatures were about 15-20°C, and spraying was carried out at the end of the day. Each crop sprayed was examined daily for the presence of insects and for any undesirable damage to any part of the plant and surrounding environment.
  • Example 3 Effectiveness of the Ivermectin/Thiovit® Combination
  • the effectiveness of the Thiovit/Ivomec combination (Composition 3) pesticide was evaluated on dahlias, a bulbous ornamental plant susceptible to diseases. Using the spraying regime described above to avoid pest and disease problems, the plant performed well under these conditions.
  • Pests on this ornamental plant vary from place to place and season to season. Pests such as aphids, thrips, whiteflies and mites of various sorts are always considered possible problems with any flower crop. Unprotected leaves are chewed by green loopes, cluster caterpillars. Earwigs and black field crickets also cause problems at times.

Examination of the plants showed severe infestation with spider mites, aphids, and other forms of pests. The plants were sprayed according to the treatment regimes described in Figures 1 and 2. The plants recovered rapidly, with early improvement being seen after five days, and full recovery of the crop within 17-20 days.
