Description

Crop safeners {Crop safeners}

The present invention relates to novel uses of the group of polymeric chemicals as crop mitigators and in particular to the use of such substances for reducing and / or preventing phytotoxicity to crops of useful plants of insecticide compositions comprising diafenthiuron. will be. Accordingly, the present invention encompasses novel insecticidal compositions comprising diafenthiuron and crop safeners, and the use of such compositions for controlling insects in crops of useful plants. In addition, the present invention encompasses combination packages of diafenthiuron and crop mitigators.

When used in the recommended proportions and dilutions, the insecticide diafenthiuron {l-butyl-3- (2,6-diisopropyl-4-phenoxyphenyl) thiourea; The Pesticide Manual 14 ^th Edition, 2006, Ed. CDS Tomlin, Pub. BCPC] effectively controls a wide range of pests without any detectable damage to the crops applied.

However, under certain climatic conditions and / or use plans, it has been reported that diafenthiuron may cause leaf redness and / or necrotic spots. Therefore, it is desirable to find a way to avoid this potential problem. As an example, since the spread of cultivation of genetically modified cotton is increasing, particularly in dry climates and where local farming is carried out using small spray doses of pesticides and single nozzle application, GM or traditional insect control approaches have been adopted. There is a need to address unexpected problems of phytotoxicity in order to provide farmers with more options for cotton pests, which are typically not controlled.

Accordingly, according to a first aspect, the present invention provides an insecticide composition comprising diafenthiuron and a crop mitigating agent.

The present invention is based on the unexpected finding that certain polymeric compounds can improve phytotoxicity caused by diafenthiuron. In particular, the polymeric compound is suitably a vinyl acetate polymer or copolymer; Acrylic polymers or copolymers; Or polyether.

Examples of suitable polymeric compounds for use in the present invention include Atlox Semkote E-135, NeoCryl A-2099, NeoCryl A-1120, NeoCryl A615, Mowilith LDM2418, Mowillit DHF 57S, TEXICRYL 17-0422, Vinamul 18160, Sandovit and Indtron (including but not limited to), these are commercially available materials to be:

Atrox Semkot E-135 (available from Croda) is an ethylene vinyl acetate copolymer.

Neocryl A-2099 (available from DSM NeoResins) is an acrylic-styrene copolymer.

Neocryl A-1120 (commercially available from DSM NeoResin) is an acrylic-styrene copolymer.

Neocryl A-615 (commercially available from DSM NeoResin) is an acrylic copolymer.

Mowillit LDM2418 (available from Celanese) is a vinyl acetate and BeoVa® (vinyl ester of versatic acid) copolymer.

Mowillit DHF 57S (commercially available from Celanes) is a vinyl acetate homopolymer.

Taxacryl 17-0422 (available from Scott Bader) is an acrylic polymer.

Bean sprout 18160 (available from Celanes) is a vinyl acetate polymer.

Sandovits (available from Syngenta India) are alkyl-aryl-polyglycol ethers.

Indtron (available from Indofil Chemicals Company) is an alkyl phenoxy polyethoxyethanol.

Such polymeric compounds are typically used as adjuvants in a wide range of industries, for example Neocryl A2099 is used for varnishing and barrier coatings, and Neocryl A-615 is used for transparent wood finishes and Used in plastic coatings. Acidity beet and indrone are prepared as surfactants for use in agrochemical formulations, while sprouts 18160 are used in fungicide formulations, while none of the chemical groups mentioned above has previously been used as (i) a crop mitigator or ( ii) it has never been used as a combination with diafenthiuron. Thus, when diafenthiuron is applied to crops as an insect control agent, in particular when the adjuvant is present at low concentrations (typically 2% v / v or less) in the application, the composition in the composition comprising diafenthiuron It is surprising that inclusion of adjuvant improves the observed phytotoxic effect. The use of an adjuvant to reduce phytotoxicity of diafenthiuron thus forms a further aspect of the present invention.

In another aspect, the present invention provides a method for reducing or preventing phytotoxicity caused by the application of diafenthiuron to a crop of a useful plant in a crop of a useful plant, the method comprising diafenthiuron, atrox Semcot From the group consisting of E-135, Neocryl A-2099, Neocryl A-1120, Neocryl A615, Mowillrit LDM2418, Mowillrit DHF 57S, Tecrylcryl 17-0422, Sprout 18160, Acid Beat and Intron Application to crops of said useful plants in combination with selected crop mitigating agents. Phytotoxic effects on plants can be visually assessed as a function of the percentage of appearance of leaves redden and / or necrosis. Crop safeners for use in the present invention are typically polymeric chemicals and will typically reduce phytotoxicity to less than 10% reddening of the leaves as compared to untreated plants. Preferred polymeric chemicals for use in the present invention will typically reduce phytotoxicity below 7%, while most preferred polymeric chemicals will typically reduce phytotoxicity below 5%. These values are approximate, since any entirely visual assessment may contain some degree of subjectivity.

Diafenthiuron for use in the present invention may be obtained as described in US Pat. No. 4328247, or may be commercially available (eg from Syngenta Crop Protection AG, Basel). It can be obtained as POLO® 50 WP, Polo 500SC or PEGASUS®.

As mentioned above, the crop mitigating agents used in accordance with the present invention are typically Atrox Semkot E-135 (available from Coroda), Neocryl A-2099, Neocryl A-1120, Neocryl A615 (all di Commercially available from SM NeoResins, Mowillitant LDM 2418, Mowillitant DHF 57S (both commercially available from Celanes), Teccyclyl 17-0422 (commercially available from Scott Bader), Vanamul 18160 (from Celanes) Commercially available), Sandoveat (commercially available from Syngenta India), and Indtron (commercially available from Indofil Chemicals Company).

Example

Example  1. Observed Phytotoxicity of Diafenthiuron in Non-Gene Cotton on  About Atrox Semkot  Effect of E-135

Field tests in three replicated plots (50 m2 each) to assess the effect of polymeric chemicals, Atrox Semkot E-135, and spray volume on diafenthiuron mediated phytotoxicity in cotton (field trial) was performed.

Cotton (cultivated varieties CIM-496) was grown to BBCH72 and treated alone or in combination with Atrox Semkot E-135, a composition comprising diafenthiuron in the form of Polo 500 SC at a rate of 250 g / ha. The crop was subjected to two applications at intervals of one week. Application was carried out using a single nozzle knapsack sprayer with a high (H) spray volume (700 L / ha) or a low (L) spray volume (200 L / ha). The composition comprising Aatrox Semcoat E-135 contained the component at 0.03% v / v.
