Stage 1

Pre-infection MOA (mechanism of action):

Before plants being infested by spider mites, prevention mechanisms can be taken with the use of DienA T. DienA T consists of 7-Epizingiberene and 9-hydroxy-10, 11-epoxy zingiberene. It establishes:

  1. Repelling and progeny-reducing effects on adult mites
  2. Exterminating effects on the larvae of T. urticae


Stage 2

Mid-infection MOA:

If a plant is already infested by spider mites, DienaS and DienaT can be used concurrently to establish mass extermination effects on spider mites. DienaS consists of spider venom peptide (SVP) fused with GNA and its eradicating mechanism is:

  1. Mites either contact or ingest leaves treated with DienaS
  2. With the help of GNA, the SVP penetrates the gut of mite and accesses its nervous system
  3. The SVP then targets the ion channels of the mites, including NaV, KV, and CaV channels The binding results in paralysis and death of mites


Stage 3

Post-infection MOA:

After being infested by mites, the plants’ immunity and condition will be severely affected. DienaH is therefore introduced to help the plants recover from their former devastation. The component of DienaH includes Harpin protein, which stimulates hypersensitive response in plants, boosts their immunity, and promotes growth.







tool  EQUIPMENT

Aiming to make our product friendlier and more accessible to customers with different backgrounds, we designed four different equipment, suitable for various scenarios.

  • 1
  • 2
  • 3
  • 4
  • 5
  • 6

DESIGNED FOR:

Horticulturists and plant lovers

Inspiration:

Considering that horticulturists and plant enthusiasts only need a small volume of pesticides for occasional prevention and elimination, we designed a handheld and detachable pesticide sprayer to facilitate their application process.

Benefits:

  1. Handheld — allows them to utilize this device easily without requiring massive physical efforts
  2. Detachable —detached spray-head and bottle allow users to clean or refill the bottle without having to maneuver the entire sprayer
  3. Portable — handheld sprayer is light and easy to carry, enabling users to treat plants in various locations
  4. Ease of use —its simple operation is accessible for both experienced gardeners and beginners

DESIGNED FOR:

Labour-intensive farms;
farms with various terrains

Inspiration:

Based on the interview with tea plantation, we discovered that the farms with various terrains are unable to apply automatic irrigation systems. Thus, we designed a backpack insecticide sprayer, aiding farmers to apply pesticides conveniently and efficiently.

Benefits:

  1. Transportable — users can apply pesticides with mobility over large areas
  2. High capacity — covers wider areas practically due to its large spray-head and volume of pesticides available
  3. Relieving the effort of farmers —instead of bearing large scale devices, users can carry our pesticide on their back
  4. Ease of use — its simple operation is accessible for all farmers

DESIGNED FOR:

Plain farms(farms located on flat land)

Inspiration:

For farmers who require large quantities of pesticide to cover extensive farmland and perform regular pest control, manual implementation is time-consuming and inefficient. As a result, we blueprinted an idea of technical pesticide drones.

Benefits:

  1. High application efficiency — large application area and reduced amount of time
  2. Lowering cost of application —declined demand for human labour leads to a decrease in hiring costs

DESIGNED FOR:

Plain farms(farms located on flat land)

Inspiration:

We refined device 3 by allowing drones to automatically identify areas infected by red spider mites while adjusting the frequencies and dates of spraying according to weather conditions.

Benefits:

  1. Higher efficiency of elimination and prevention — due to the regional variation of spider mites, the elimination process can be more efficient and precise if temperature, humidity, and target regions are taken into consideration
  2. High application efficiency —large application area and reduced amount of time
  3. Lowering cost of application —only infected areas are detected and targeted, eliminating the possibility of wasting pesticide on unnecessary healthy plants

DESIGNED FOR:

Floral designer for service industry;
the horticulturists and plant lovers

Inspiration:

Through communicating with floral designer, we recognized her concerns, which is that the process of precaution was hindered as she has to report it to the hotel managers and wait for approval. To save her time and resolve the issues, we determined to design a device which allows to add the pesticides automatically into soil without the need of spraying.

Benefits:

  1. Time-saving — Automatic process reduces people’s time and effort for plant caretaking
  2. Promote prevention — people may inevitably overlook the process of prevention. With our design’s help, the infestation of spider mites can be effectively prevented feasibly
  3. Environmentally friendly —reused containers reduces plastic waste
  4. Accessible for the low income group — considering that the low income group may be excluded from high-price device, we designed it with a simple composition of a plastic bottle and two cotton sticks. Various groups of the population may utilize our design with minimal financial burden
  5. Ease of use —its simple operation is accessible for all experienced gardeners and beginners

DESIGNED FOR:

Individual plant lovers

Inspiration:

Derived from our interview with an individual plant lover, we expanded our design with the aim of carriageable convenience. Thereby, the ideology of individual package containing powdered pesticide guided our thoughts.

Benefits:

  1. Carriageable — individual powdered package are minature in volume and weight. Target consumers may carry our product feasibly and treat plants with least energy
  2. Ease to store — multiple small-scale packages can prevent cross-spoiling or damaging of our pesticide
  3. Accessible for low income group —reduced needs for costly packaging and volumous transportation lowers our valuation to a friendly price
