Definitions

  • the present invention relates to novel aqueous agrochemical compositions, their use for foliar application, their use at conventional spray volumes, their use at low spray volumes, their use by unmanned aerial or land vehicles (UAV), and their application for controlling agricultural pests, weeds or diseases and reducing the wash-off of active ingredients by rainfall, as well as reducing the rebound of droplets, in particular on waxy leaves.
  • UAV unmanned aerial or land vehicles
  • Another invention relates to adjuvant combination for agrochemical formulations with low spray volumes.
  • agrochemical compounds used in the compositions according to the instant invention are selected from the group comprising herbicides, fungicides, insecticides, host defence inducers and safeners, as well as mixtures thereof.
  • a key requirement of agrochemical formulations is to deliver active ingredients as effectively as possible to the target while minimising off-target losses to the environment. Designing formulations to achieve this is complex since optimising a formulation for one property often has unwanted effects on other important properties. For example formulants that improve the wetting of crops and the biodelivery of active ingredients often enhance losses to the environment through wash-off by rainfall.
  • aqueous formulation suspensions and specific surfactant combinations have been designed which surprisingly give enhanced biological control of target pests, excellent wetting and coverage of the crop and low off-target losses to the environment including low rebound of the spray from waxy crops and low wash-off by rainfall.
  • Formulations known in the prior art generally exhibit at least one of the following disadvantages like high wash-off of the active ingredient by rainfall, poor coverage at lower spray volumes, as well as high rebound, in particular on waxy leaves, or combinations thereof.
  • a further requirement of the formulations are that they exhibit excellent physical stability and have a shelf life of two or more years over a wide range of climates. Accordingly there is still a need to develop storage stable compositions which deliver active ingredients as effectively as possible to the target, exhibit excellent wetting and coverage while minimising off-target losses to the environment including rebound of the spray from waxy crops and wash-off by rainfall at both conventional spray volumes and low spray volumes including application by UAVs.
  • the object of the present invention was therefore to provide highly storage-stable aqueous suspension concentrates, aqueous suspensions, and capsule suspensions which show excellent biological performance, excellent wetting and coverage of the crop, low rebound of the spray and low wash-off by rainfall for use in foliar applications at conventional spray volumes and low spray volumes including application by UAVs.
  • designing such formulations is a challenge since these objectives cannot be simply obtained by adding components of each functionality together since they are often antagonistic and/or unstable, and designing formulations that avoid these antagonisms and instabilities is complex.

Description

Agrochemical formulation with enhanced performance and enhanced performance at low spray volumes and by UAV application
The present invention relates to novel aqueous agrochemical compositions, their use for foliar application, their use at conventional spray volumes, their use at low spray volumes, their use by unmanned aerial or land vehicles (UAV), and their application for controlling agricultural pests, weeds or diseases and reducing the wash-off of active ingredients by rainfall, as well as reducing the rebound of droplets, in particular on waxy leaves.
Another invention relates to adjuvant combination for agrochemical formulations with low spray volumes.
The agrochemical compounds used in the compositions according to the instant invention are selected from the group comprising herbicides, fungicides, insecticides, host defence inducers and safeners, as well as mixtures thereof. A key requirement of agrochemical formulations is to deliver active ingredients as effectively as possible to the target while minimising off-target losses to the environment. Designing formulations to achieve this is complex since optimising a formulation for one property often has unwanted effects on other important properties. For example formulants that improve the wetting of crops and the biodelivery of active ingredients often enhance losses to the environment through wash-off by rainfall.
In this invention aqueous formulation suspensions and specific surfactant combinations have been designed which surprisingly give enhanced biological control of target pests, excellent wetting and coverage of the crop and low off-target losses to the environment including low rebound of the spray from waxy crops and low wash-off by rainfall.
Formulations known in the prior art generally exhibit at least one of the following disadvantages like high wash-off of the active ingredient by rainfall, poor coverage at lower spray volumes, as well as high rebound, in particular on waxy leaves, or combinations thereof.
An important requirement of the formulations, also in view of the limited cargo load of UAVs, is that they deliver enhanced performance not only at conventional spray volumes, typically 80 to 1000 1/ha, but also at reduced spray volumes, typically 2 to 60 1/ha, preferably 4 to 25 1/ha, where new application practices such as UAV application including unmanned helicopters and drones can offer faster and lower cost application, as well as spot applications if required. There is an urgent need in the industry for formulations which can fulfill this requirement.
A further requirement of the formulations are that they exhibit excellent physical stability and have a shelf life of two or more years over a wide range of climates. Accordingly there is still a need to develop storage stable compositions which deliver active ingredients as effectively as possible to the target, exhibit excellent wetting and coverage while minimising off-target losses to the environment including rebound of the spray from waxy crops and wash-off by rainfall at both conventional spray volumes and low spray volumes including application by UAVs.
The object of the present invention was therefore to provide highly storage-stable aqueous suspension concentrates, aqueous suspensions, and capsule suspensions which show excellent biological performance, excellent wetting and coverage of the crop, low rebound of the spray and low wash-off by rainfall for use in foliar applications at conventional spray volumes and low spray volumes including application by UAVs. However, designing such formulations is a challenge since these objectives cannot be simply obtained by adding components of each functionality together since they are often antagonistic and/or unstable, and designing formulations that avoid these antagonisms and instabilities is complex.
Therefore, the objective of the instant invention was solved by the present invention with agrochemical compositions comprising: an aqueous dispersion of a) at least one agrochemical active compound, which is solid at room temperature,

Examples
A) Methods
The formulations were prepared according to the following methods.
Method 1:
The method of the preparation of suspension concentrate formulations are known in the art and can be produced by known methods familiar to those skilled in the art. A 2% gel of the xanthan (f) in water and the biocides (h) was prepared with low shear stirring. The active ingredient(s) (a), non-ionic and anionic dispersants (e), a portion of the antifoam (g) and other formulants (h) were mixed to form a slurry, first mixed with a high shear rotor-stator mixer (Ultra-Turrax®) to reduce the particle size D(v,0.9) to approximately 50 microns, then passed through one or more bead mills (Eiger® 250 Mini Motormill) to achieve a particles size D(v,0.9) typically 1 to 15 microns as required for the biological performance of the active ingredient(s). Those skilled in the art will appreciate that this can vary for different active ingredients. The remaining components: mono-and diesters of sulfosuccinate metal salts (b), polyalkyleneoxide modified heptamethyltrisiloxane (c), emulsion polymer or polymer dispersion (d), portion of the antifoam (g) and xanthan gel prepared above were added and mixed in with low shear stirring until homogeneous. Finally the pH was adjusted to 7.0 (+/- 0.2) with acid or base (h).
The formulation stability was determined according to the following method.
Method 2:
The stability of the example formulations was determined by storing samples at a range of temperatures including 45 °C, 40°C, 30°C, RT (22°C), -10°C and -15/30°C cycling (7 days cycle) over storage times up to 24 months. They were then examined visually for any thickening, gravitational separation (total height of sample H and height of sediment phase Ht), aggregation of the active ingredient particles in a 1% dilution in water in a microscope, particle size (D90) from laser diffraction (Malvern Mastersizer) and viscosity at a shear rate of 20s 1 and a temperature of 20°C. Storage tests at higher temperatures (40°C and 45 °C) over shorter time scales may be used as accelerated storage tests for an indication of product stability at normal temperatures (20°C and 30°C) and normal product shelf life (2 years). The D90 is the particle diameter where 90% of the particles by volume are less than this value. The viscosity may be measured with a rotational shear rheometer according to CIPAC MT192.

Example 1:
Formulations were prepared with the following recipes: Table IX: Recipes 1, 2 and 3.
Figure imgf000025_0002
Figure imgf000026_0001
The method of preparation used was according to Method 1.
The recipes 1 and 2 according to the invention exhibited good stability during storage testing for up to 2 years according to Method 2. Table X: Storage stability for recipes 1 and 2.
Figure imgf000027_0001
The biological performance of recipe 1 (according to the invention) and recipe 3 was compared outdoors in paddy rice at spray volumes of 400 to 600 L/ha. The biological efficacy for leaf and neck rice blast disease was assessed 7-15 days after the second foliar spray application (assessment 1) and again after 19- 22 days (assessment 2) and the yield measured at harvest. Table XI: Biological efficacy and yield results from example 1.
Figure imgf000028_0001
The results show that recipe 1 according to the invention gave superior biological control and an increased yield compared to the reference recipe 3. Example 2:
In an other example 1 litre each of recipes 2 and 3 were diluted in 7 litres of water and sprayed by a Maruyama MMC940AC drone fitted with two Yamaha flat fan nozzles flying at a height of 2 m at an application rate of 8 1/ha onto leaf sections taken from rice, soybean and com plants. A fluorescent marker (Tinopal OB®) was added and the spray coverage determined from analysis of images obtained under UV illumination. The drone flew at a height of 2 m and a speed of 15-20 km/h.
Table XII: Leaf coverage after srpay application by drone at 8 1/ha.
Figure imgf000028_0002
The results shown in table XII demonstrate that recipe 2 (according to the invention) showed a much improved wetting and coverage of each of the leaf surfaces. Example 3:
In another example recipes 2 and 3 were diluted at a rate of 1 litre of SC in 7 litres of water and sprayed by a Maruyama MMC940AC drone fitted with two Yamaha flat fan nozzles flying at a height of 2 m at an application rate of 8 1/ha onto rice plants (cv. Koshihikari) in pots at the growth stage of full tillering with the same application conditions as above. The rice plants were inoculated with rhizoctonia solani 17 days after application followed by incubation at 25 °C and 100% relative humidity for 7 days under dark conditions. The rice plants were then grown in a greenhouse for 18 days and assessed for disease control.
Table XIII: Disease control after srpay application by drone at 8 1/ha.
Figure imgf000029_0001
The results in table XIII demonstrate that recipe 2 (according to the invention) gave enhanced control of disease.
Example 3b:
In an example recipes 2 and 3 were diluted at a rate of 1 litre of SC in a range of water volumes ranging from 1200 1/ha to 4 1/ha and along with a small amount of a fluorescent label and were sprayed by a back- pack sprayer onto outdoor rice plants (japonica) fitted with (Teejet) Conejet® TXVS nozzles (1200-600 1/ha TXVS-8, 300-4 1/ha TXVS-2) at the growth stage of ripening. The spray deposits on isolated rice leaves were photographed under UV illumination and the coverage of the spray and mean spray deposit area was measured using ImageJ image analysis software (Fiji package, www.fiji.com).
Table XIV : Leaf coverage and spray deposit area at different spray volumes.
Figure imgf000029_0002
Figure imgf000030_0001
The results in table XIV demonstrate that recipe 2 (for the described sprayable liquid for low volume spray application) remarkably gave significantly improved coverage at 50 to 4 1/ha compared to the reference recipe 3. At 100 1/ha the coverage was significantly lower for recipe 2 demonstrating the importance of low spray volumes less than or equal to 50 1/ha for achieving a significantly higher leaf coverage of the spray mixture. At 200 to 1200 1/ha a higher coverage was observed from the greater spray volume. Importantly, recipe 2 sprayed at 4 to 50 1/ha achieved a comparable coverage to the reference recipe 3 at 600 1/ha demonstrating that the described sprayable liquid for low volume spray application can achieve comparable coverage to reference formulations sprayed at much higher conventional spray volumes. However, the reference formulation 3 did not achieve comparable coverage at low spray volumes less than 100 1/ha.
The same enhancement of coverage can be seen with the mean spray deposit area, recipe 2 (for the described sprayable liquid for low volume spray application) remarkably also produced spray deposits with significantly higher spreading between 50 and 4 1/ha. Higher spray volumes of 100 and 200 1/ha produced deposits with much lower areas as did the reference recipe at 4 to 300 1/ha. The results from table XIV are plotted in Fig. 2.
Both of these results demonstrate the advantage of the described sprayable liquid at low volume spray application between 4 and 50 litres per hectare for application by an unmanned aerial vehicle as described here.
Example 4:
Formulations were prepared with the following recipes: Table XV : Recipes 4, 5 and 6.
Figure imgf000031_0001
Figure imgf000032_0001

Figure imgf000033_0001
Example 5:
In another example Nativo® WG (Bayer AG) containing 25%w/w trifloxystrobin and 50%w/w tebuconazole and Recipe 5 were sprayed onto greenhouse grown rice plants (growth satge 21) at a spray rate of 0.2 kg/ha for Nativo® WG and 0.5 1/ha for recipe 5 in a water volume of 100 1/ha.
Table XVII: Amount of active ingredient remaining on and in the plants after spray application.
Figure imgf000033_0002
The results show that recipe 5 according to the invention demonstrated significantly higher retention on rice plants than Nativo® WG. Example 6: Low spray volumes
In an example recipe 4 for the described sprayable liquid for low volume spray application and the commercial product Nativo® 300 SC (Bayer AG, registration number L8942 South Africa, code 102000008381) which contains 100 g/1 of trifloxystrobin and 200 g/1 of tebuconazole were applied by spray application to paddy rice using a low spray volume of 60 1/ha and assessed for control of neck blast disease after two applications. The treated crops were then harvested and the yield measured. Table XVIII: Biological results for recipe 4 and Nativo® SC.
Figure imgf000034_0001
The results show that at the low spray volume of 60 1/ha recipe 4 according to the invention gave both significantly higher disease control and increased yield compared to the commercial reference Nativo® SC.
