## Abstract

A low viscosity agricultural adjuvant for spraying syrup comprising emulsifying agents, surfactants, suspending agents, defoamer, clays and water. This invention is directed to the agricultural sector and it is an adjuvant that can be classified as an activator and modifier of spraying and other modifiers. The adjuvant when added to the agricultural spray syrup, assists in the compatibility of phytosanitary products used for the formation thereof. This invention avoids the formation of possible organic and inorganic scale, which can affect the spraying equipment. The invention confers high syrup conditioning capacity and provides a homogeneous and fluid syrup preparation, with high efficiency from the outlet of the spray nozzle to the deposition of droplets in the crops.

## Claims

### Claim 1

A low viscosity agricultural adjuvant for spraying syrups, comprising:
10% to 30% by weight of emulsifying agents,
7% to 25% by weight of surfactants,
0.15% to 1.0% by weight of suspending agents,
2.0% to 20% by weight of a silicone defoamer,
5.0% to 20% by weight of clays, and
50% to 80% by weight of water.

### Claim 2 (depends on 1)

The low viscosity agricultural adjuvant for spraying syrups according to claim 1, wherein the emulsifying agents and surfactant agents are selected from a group comprising ammonium lauryl ether sulfate, sodium lauryl ether sulfate, triethanolamine lauryl ether sulfate, sodium lauryl ether sulfosuccinate, ammonium lauryl sulfate, sodium lauryl sulfate, ethoxylated alcohols, ethoxylated and propoxylated alcohols, ethoxylated fatty alcohols, ethoxylated ketostearyl alcohol, ethoxylated stearyl alcohol, ethoxylated istridecyl alcohol, ethoxylated and phosphate istridecyl alcohol, ethoxylated and sulfated istridecyl alcohol, ethoxylated lauryl alcohol, ethoxylated oil, linear alkylbenzene sulfonic acid, sulfonic acid of alkylbenzene mixtures, lauryl benzene sulfonic acid, and dodecylbenzene sulfonic acid.

### Claim 3 (depends on 1)

The low viscosity agricultural adjuvant for spraying syrups according to claim 1, wherein the suspending agents are selected from a group comprising arabic gum, tragacanth gum, locust bean gum, carrageenan gum, damar gum, xanthan gum, and gellan gum.

### Claim 4 (depends on 1)

The low viscosity agricultural adjuvant for spraying syrups according to claim 1, wherein the clays are selected from a group consisting of sodium bentonites, calcium polycationics, attapulgite, kaolinite, sepiolite, smectite, montmorillonite, and zeolite.

### Claim 5

A method of manufacturing a low viscosity agricultural adjuvant for spraying syrups comprising the steps of:
mixing water and a suspending agent in a mixer of stainless steel to form a mixture;
heating said mixture during mixing;
allowing said mixture to cool;
adding a silicone defoamer, an emulsifying agent, a clay, and a surfactant to said mixture in said mixer and operating said mixer to form said low viscosity agricultural adjuvant, wherein said low viscosity agricultural adjuvant comprises;
10% to 30% by weight of said emulsifying agent,
7% to 25% by weight of said surfactant,
0.15% to 1.0% by weight of said suspending agent,
2.0% to 20% by weight of said silicone defoamer,
5.0% to 20% by weight of said clay, and
50% to 80% by weight of said water.
