Dry Flowable (DF)

 

 

Description

 

Dry Flowable (DF) is a solid formulation prepared by wet milling (like the process of SC) followed by spray drying or fludized bed granulation to remove moisture.

 

Benefits

 

● Non-dusty, freely flowable, reduced packaging and transportation costs

● Spontaneous dispersion upon dilution with perfect blooming effect, appropriate for aerial application

● A smaller droplet particle Achievable for better efficacy

● Suitable for continuous and large scale production, low labor intensity and clean production

● High loading of active ingredients

 

Limitaions

 

● One-time investment of facilities and technical threshold is high, suggest to use this production method when reach a certain production scale.

Application of Dry Flowable

 

 

Lignosulfonates with surfactants. These particular products act as a dispersant to suspend the particles of a formulation, work as a binder to help strengthen the granules and as a disintegrant to help break the granules apart when diluted in water. The addition of surfactants offers advantages such as formulation flexibility, better wetting, greater performance with high silica levels and improved compatibility. They can also improve the water tolerance and fertilizer compatibility of a tank mix.

 

Features of Dry Flowable

 

It is a polymer dispersant with a special lipophilic group and certain rigidity. It has good compatibility with both high-loading lipophilic pesticides and low melting point pesticides due to its strong lipophilicity. It also has high hand water resistance and excellent dispersibility at different temperature. The product itself is not sticky and will not cause hardening of formulation.

Production Method of Dry Flowable

A method for preparing a pesticide dry suspension, comprising: first selecting a high-performance dispersant to prepare a medium-high content pesticide suspension, then adding a water-soluble high-temperature resistant dispersant and a water-soluble disintegrant to the suspension system for shear mixing, and then spray drying to obtain a dry suspension product. This method is mainly suitable for preparing a high-content suspension with a difficult technical system, such as a low-melting-point technical with a melting point below 80°C, a highly water-soluble technical with a solubility in water greater than 0.5g/L, and a technical that easily forms hydrogen bonds and water clusters with water. By the above method, the preparation of the dry suspension can increase the ratio of the solid content in the suspension slurry, reduce the energy consumption of spray drying, and increase the granulation rate and particle size of the dry suspension.

FAQ

Q: What is a dry flowable?

A: Dry flowable (DF) or Water dispersible granules (WDG) formulations are similar to wettable powders except that the powders (clay particles) are formed into tiny spheres. They do not tend to pack together so they “flow” easily from the product container.

Q: What is a dry flowable pesticide?

A: Dry flowables—Or water dispersible granules, as they are sometimes called—are manufactured in the same way as wettable powders except that the powder is aggregated into granular particles. They are diluted with water and applied in a spray exactly as if they were a wettable powder.

Q: What is dry flowable sulfur?

A: It is an 80% fungicide and acaracide with sulfur particles of 10 microns or less, providing more optimal coverage on crops. The particle size of the dispersed sulfur ranges from 0.1 - 10.0 microns with an average particle size of 3.0 microns.

Q: What is dimethomorph 50 WP used for?

A: It is a systemic fungicide that protects plants from fungi in the water mold family, such as Late blight and Downy mildew. It moves up the treated plant stem to growing leaves. It also has anti-sporulate activity, which helps to prevent the spread of blight between plants.

Q: What is 50 WP in fungicide?

A: Captan 50% WP is a fungicide of micronized particle size for use in water as a spray for the control of certain fungus diseases of fruit, vegetable seeds, and ornamental crops. It gives excellent protection against a wide variety of fungal infections in crops, both at the seeding stage and in mature plants.

Q: How does dimethomorph work?

A: When applied as a foliar spray, dimethomorph penetrates the leaf surface and is translocated within the leaf to provide protectant action against plant pathogenic Phytophthora species and a number of downy mildew diseases of fruit, vegetables and potatoes.

Q: Is dimethomorph a systemic fungicide?

A: Application Sites: Dimethomorph is a systemic morpholine fungicide for use on potatoes. Its mode of action is the inhibition of sterol (ergosterol) synthesis.
