Description

COMPOSITION AND METHOD FOR TREATING NEMATODES
The present invention relates to a method for controlling and combating nematodes. The present invention further relates to a nematicidal composition for achieving the same.
Nematodes are small worms which are almost transparent and invisible to the naked eye. Nemotades are generally from 0.3 to 3.0 millimeters in length. Although nematodes are small in size, they cause about 12% of the annual losses to agricultural production, which corresponds to millions of dollars in lost crops (SASSER & FRECKMAN, 1987). Nematodes typically feed on the roots or shoots of plants. They reduce absorption and transportation of water and nutrients. A range of plants can be host to nematodes, including such crops as sugarcane, soybean, corn, coffee and cotton. Nematodes attack in the field in the form of spots/coppices and rarely spread throughout the field. The plants being attacked by nematodes may show symptoms of nutritional deficiency and reduced or slower development than healthy plants. Sampling and carrying out laboratorial analyses of soil and roots are required for confirmation of the existence of nematodes.
Current methods for controlling nematodes are very limited. One example of a commonly applied treatment is exposing infested soil to heat by the use of steam. However, steam treatment is technically difficult and costly for general application in the field.
An alternative to steam treatment is to use chemical nematicides. An issue with using chemical nematicides is the danger associated with the production and use of the active chemical nematicide ingredients. The active ingredients can be toxic and may lead to death. As a result, a number of countries have restricted the use of certain nematicides, for example methyl bromide.
Accordingly, there is a significant need for an improved technique for controlling nematodes in crops, in particular a nematicidal composition and a method of controlling nematodes, as well as other plant pests and pathogens. It would be an advantage if the nematicidal composition is easy to use and less costly to produce and employ than known treatment techniques.
The present invention provides a safe and effective way to control and combat nematodes.
It has now surprisingly been found that a fertilizer composition comprising one or more amino acids and one or more micronutrients is active results in controlling and combating a wide range of nematodes in crops. In particular, the aforementioned fertilizer composition exhibits a high activity in controlling Pratylenchus zeae, Meloidogyne javanica, Pratylenchus brachyurus, Meloidogyne exigua, Meloidogyne incognita, Heterodera glycines, Rotylenchulus reniformis nematodes in a wide range of crops, such as sugarcane, soybean, coffee, corn and cotton.
Accordingly, in a first aspect, the present invention provides a nematicidal fertilizer composition comprising one or more amino acids and one or more micronutrients.
In a further aspect, the present invention provides a method for controlling nematodes in plants at a locus, the method comprising applying to the locus one or more amino acids and one or more micronutrients.
In a still further aspect, the present invention provides the use of a combination of one or more amino acids and one or more micronutrients in the control of nematodes.
In general, the present invention provides a method for controlling nematodes comprising applying to a plant, a plant part or surrounding an effective amount of an antinematode composition comprising one or more amino acids and one or more micronutrients. The present invention is of particlar use for controlling Pratylenchus zeae, Meloidogyne javanica, Pratylenchus brachyurus, Meloidogyne exigua, Meloidogyne incognita, Heterodera glycines, Rotylenchulus reniformis.

In use of the present invention, the rates of application of the combination of amino acids and micronutrient may vary, for example, according to such factors as the type of use, the type of plants, temperature, humidity, the type of nematode being controlled, soil type, and pH of the soil. The application rate of the combination of amino acids and micronutrients for a given set of conditions can readily be determined by routine trials. The formulations, either straight, that is undiluted, or diluted with a suitable solvent, especially water, plants, may be applied to plant parts and/or the surrounding by methods known in the art, including spraying, pouring, dipping, injection, irrigation, immersing and the like.
Generally, the combination of one or more amino acids and one or more micronutrients may be applied to the locus being treated at a range of application rates. The application will depend upon such factors as the type of treatment being applied.

In the spray treatment, amino acids may be applied at an application rate of from 5 gram per hectare (g/ha) to 2000 g/ha, more preferably from 10 g/ha to 1000 g/ha, still more preferably from 10 to 600 g/ha.

The amino acids and micronutrients can be applied to the plants, plant parts and/or surrounding where control is desired either simultaneously or in succession at short intervals, for example on the same day. The amino acids and micronutrients may be applied to the plant, plant parts, or surrounding in any order. Amino acids and micronutrients may be applied just once or a plurality of times, for example, from 2 to 5 times, more preferably 3 times.
In the event amino acids and micronutrients are applied simultaneously in the present invention, they may be applied as composition containing both the amino acids and the micronutrients, in which case the amino acids and the micronutrients may be obtained from a separate formulation source and mixed together, known in the art as a tank-mix, a ready-to-apply, a spray broth, or a slurry, or the amino acids and the micronutrients may be obtained as a single formulation mixture source, known in the art as a pre-mix, a concentrate, or a formulated product. An example of such a formulated product is the composition described above and hereinafter.
The compositions according to the present invention are distinguished by being especially well tolerated by plants and by being environmentally friendly.
Embodiments of the present invention are now described, for illustrative purposes only, by way of the following examples. Where not otherwise specified throughout this specification and claims, percentages are by weight.
Example 1 - Pratylenchus zeae - Sugarcane
A nematode inoculum was prepared from a pure subpopulation of Pratylenchus zeae recovered from sugarcane crops located in Pacaembd-State of Sao Paulo-Brazil. The subpopulation was multiplied from corn plants (Zea mays L.) ΌΚΒ 390 PRO' in clay recipients in a greenhouse. The subpopulation was previously identified based on morphological characters of adult females mounted in temporary slides by using a dicotomic key created by SANTOS et al. (2005).
ml_ samples of the compositions summarised in Table 1 below were applied uniformly on the soil and around the roots at the rate of 2L/ha. Thereafter, the roots of the sugarcane were inoculated with 10 ml_ of a suspension cotaining Pratylenchus zeae in various stages of development, after which the roots were covered with soil. 5 replicates were carried out.
Table 1
Samples: Weight (%) by the weight of the antinematode composition
1. Anti-nematode composition 12% amino acids; 10% micronutrients (zinc sulphate, sodium borate complex, iron sulphate, manganese sulphate and copper sulphate); 10% auxiliaries (including solvent, surfactant and stabilizer) in water
2. Anti-nematode composition 12% amino acids; 10% micronutrients (zinc sulphate and sodium borate complex); 10% auxiliaries (including solvent, surfactant and stabilizer) in water
