Registration of safer chemicals
Proportion of pesticide active ingredients that are considered to be safer (biological chemicals and reduced-risk conventional chemicals) has steadily increased over the last several years.

BOTANICAL PESTICIDES
ScopeIndigenous; most suited rural
milieu
· Biodegradable – Green
· Time tested through co-evolution
· Least side – effects
· Complex m.o.a; slow-resistance development
· Useful lead-templates for potent version
Ideally suited to biotechnological innovations & integration
Biodiversity
Drawback Action “ayurvedic” not
allopathic Situation / location /target
specific Low level & stability No volume and sales /
turnover - No MNC would prefer
Low yield / chemo-type, genotype, eco-type variations; plant part, age; storage conditions critical
Crude works better; synergistic

Push-pull or Stimulo – Deterrent Diversionary Strategy
Push Pull
Away from the crop Traps / trap crops
Masking of host attraction; (1R,5S) Myrtenal for Aphids fabae); Methyl salicylate against cereal aphids
Host attractants (Isothiocyanates of oilseed rape for the seed weevil and cabbage stem flea beetle
Repellents, antifeedants, oviposition deterrents
Aggregation, sex and oviposition semiochemicals
Attractants for predators and parasitoids; e.g. Faba beans produce 6-methy-5-hepten-2-one, an attractant for aphid parasitoid

Botanical Pesticides: IPR and Policy Issues
Framing pesticide policy to protect human and ecosystem health
Patentability of the product should be considered. Prior publication of pesticidal properties of a compound could cause patent problem
Patenting synthetic analogues with no mention of the natural source of the chemical family might be safer than patenting the natural product
Softening registration requirements for natural products

Gene expression profiling, a revolutionary tool in herbicide
discoveryGene Expression Profiling (GEP) with DNA microarrays (chips) is a new technology used to measure changes in the entire transcriptome, i.e. full complement of active genes, of an organism in a single experiment.
A catalogue of genetic fingerprints of the plant Arabidopsis thaliana, is created and each fingerprint being characteristic for a single herbicidal MoA is then used to rapidly classify herbicidal compounds from Ultra High Throughput Vivo Screening (UHTVS) according to their MoA.
Besides GEP also provides the opportunity to identify the affected metabolic pathway which is a first step towards the identification of novel herbicidal targets. Additionally GEP can identify the MoA of pro-drugs, which cannot be elucidated by conventional biochemical methods.
GEP provides insight into the interactions of any herbicidal compound with the entire plant metabolism with unprecedented accuracy and completeness.

Cyclotides are a structurally unique family of small disulfide-rich proteins embedded with highly stable structural motif and showing a broad range of roles in plant defense such as proteinase inhibition, anti-bacterial, anti-viral effects and insecticidal activities.

MADHUCA INDICA (MAHUA)(Family Sapotaceae)
• Mahua valued for its oil bearing seeds and flowers
• Traditionally utilized for alcoholic beverage production
• Seeds kernel constitute over 50% non-drying oil (66% total unsaturated and 33% total saturated)
• Mahua seed kernel contains 2.5% toxic saponin content which must be removed for utilizing mahua cake as animal feed
• Efforts have been made to separate saponins from defatted seed cake for possible use as pest control agents

Photo-activated xanthotoxins from Ammi majus seeds
Xanthotoxins are known for the treatment of vitiligo, leucoderma asthma, angina and digestive system disorders
The plant is widely cultivated in India for these bioactive furanocoumarins which are used in the treatment of vitiligo and psoriasis
Like other many photo-activated compounds these furacoumarins may find use in pest control

Isolation and LC analysis of xanthotoxins from Ammi majus seeds
The seed contains furanocoumarins (5-, and 8-methoxypsoralens), which stimulate pigment production in skin that is exposed to bright sunlight
Process has been developed and standardized for the efficient extraction of furanocoumarin from seeds using fluorinated solvents such as phytosols. Extractions were completed within three cycles
LC method has been standardized for the analysis of furanocoumarins using UV detector (230 nm), RP-18 column and acetonitrile as solvent system
