RNA spray candidates designed and greenhouse-tested for Indian crop pest firms
TL;DR Strandfast designs double-stranded RNA sprays that switch off one essential gene in one pest, and proves them in insectaries and greenhouses. Indian agrochemical companies pay for discovery projects and license the winners, because they already own registration teams and dealer networks that a startup lacks.
Indian farmers keep losing chemical and genetic tools to resistance. Pink bollworm caused almost no green boll damage on Bt cotton from 2002 to 2013, but infestations above the economic threshold peaked across many sites in 2017, and in the north zone they rose again to a peak in 2023[1]. Each lost tool pushes growers towards more sprays of broad-spectrum chemicals.
A spray that targets a single gene in a single species would leave bees, predators and the farmer alone. That promise is real, but no Indian company sells one yet and the science has sharp limits.
What it does, in regulatory terms: crop-protection research service. Any product a client sells is a pesticide needing CIB&RC registration under the Insecticides Act 1968. We found no India-specific guideline for sprayed RNA, so expect case-by-case review[2].
Strandfast picks pests where RNA works best. Beetles respond well, sucking pests vary, and caterpillars often respond poorly[3]. So pink bollworm is a bad first target despite the pain, which I know isn't what cotton growers want to hear. For each pest the team chooses target genes and screens candidates in an insectary, then runs greenhouse trials with a client's formulation team. Indian labs have already cut whitefly survival by 60–100% in lab tests with RNA loaded on clay nanosheets[4], which shows the approach can work locally.
We reframed the seed, which pitched a farmer-facing platform. Sprayed RNA breaks down fast on leaves, about 95% gone within three days[3], and it is still costly to make. A small company should sell discovery to firms that can carry the registration and launch costs.
The payer is the R&D or product head at an Indian agrochemical or biologicals company. They'd pay per discovery project, with milestone fees and a royalty if a candidate reaches market. There's no public price for this kind of contract in India, so the fee level is an assumption to test.
RNA sprays have crossed from lab to market abroad. The US EPA registered ledprona, a sprayed RNA against the Colorado potato beetle, in December 2023[5]. A US RNA company followed with an RNA treatment for honeybee mites in September 2025[6]. Production costs are falling, with cell-free methods claimed below US$1 a gram (about ₹97)[3].
There is no public figure for Indian spending on RNA-based crop protection. The firmest signals are the two US products above[5][6] and documented resistance in a major Indian pest[1]. Treat the wider Indian crop-protection market as adjacent context only, and I didn't verify a figure for it this time.
That US RNA company makes and sells RNA sprays in the US and has filed in Europe and Brazil[6]. A global seed major sells maize that makes its own RNA against rootworm, a different route that India would review under its GM rules[3]. In India, university labs publish on whitefly and other pests[4], but we found no company offering RNA discovery to agrochemical firms. That is the gap.
| Difficulty | Hard (61/100) |
| Starting capital | ₹3–5.5 Cr |
| Time to launch | 18–24 months |
Rearing pests year-round, picking genes that kill the pest but match nothing in bees or predators, and keeping RNA alive on a leaf for long enough are the technical hurdles. The commercial hurdle is simpler. Clients will wait for greenhouse data before paying much.
Yes. Anything sold to farmers is a pesticide, so the registration gate is real.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI judge environmental or human safety. Those calls rest on real studies and the regulator's review.

Here's what can go south -
I'd back a team of insect molecular biologists with industry contacts and the patience for slow science. If you want a farmer brand quickly then this isn't it. Before you raise, prove that one candidate kills a target beetle or sucking pest in greenhouse trials and stays active on leaves for a week, and that one firm will pay for the next stage.
Plan for roughly ₹3–5.5 Cr for a molecular lab, an insectary and greenhouse trials.
Yes. Any product sold needs CIB&RC registration under the Insecticides Act 1968, and there is no India-specific guideline for sprayed RNA yet.
Yes. The US has already registered a sprayed RNA product. Check how your own pesticide regulator classifies RNA before you plan studies.

Thinking about building Strandfast or something close to it? The make-or-break work is getting RNA to last on a leaf and finding a client willing to carry registration, and I can help you plan that pitch. If you need a hand, you know where to find me. Talk to Yash →
