These are the substances which are added in the formulation along the therapeutic agent so as to impart specific qualities in the formulation.
These are have very little or no therapeutic value but are necessary in the manufacture of various dosage forms.
Purposes served by Additives:
Provide bulk to the formulation.
Facilitate drug absorption or solubility and other pharmacokinetic considerations.
Aid in handling of “API” during manufacturing .
Provide stability and prevent from denaturation etc

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
2. INSECTICIDE FORMULATIONS
• AI = active ingredient, chemicals that are responsible for the pesticidal effect
• Inert ingredient = any substance in a pesticide formulation having no pesticidal action
• Formulation = the way a pesticide is prepared for practical use
• Carrier = inert liquid or solid added to an active ingredient to prepare a pesticide formulation
3. What?
Formulations of Insecticides: processing of the toxic substance to improve its
properties of storage
handling
application
effectiveness and
safety to the applicator and environment and profitability
It is the final physical condition in which insecticide is sold
Why?
• To come into direct contact with the pest or leaf
• Uniform and persistent deposit upon the plant surface
• Since very small quantity of toxicant is required to be distributed over a large area
• Formulated in a form suitable for use as a spray, dust or fumigant
4. 1. Dusts (D):
• ready to use insecticides in powder form
• Diluted by a suitable finely divided carrier
• Carrier may be an organic flour or pulverized
mineral or clay
• Toxicant ranges from 0.15 to 25%
• Particle size is less than 100 microns
• With Decrease in particle size, the toxicity increases
• Easy to apply, less labour and water is not necessary
• Loss of chemical occurs due to wind drift
• Done in calm weather, early morning hours when the
plant is wet
• Eg. HCH 10% dust; Endosulfan 4% D
2. Granules or Pelleted insecticides(G):
• Ready to use granular forms
• Composed of a base fused with the toxicant
• Particle size 0.25 to 2.38 mm
• Contains 1 to 10% concentration
• Applied in water or whorls of plants or in soil
• Action may be by vapour or systemic
• very little drift and no undue lose of chemical
• Undesirable contamination is prevented
• Residue problem is less
• Release of toxicant is achieved over a long period
• Easy for application as water is not required
• Less harmful for natural enemies
Eg: Carbofuran 3G, Phorate10 G, Cartap hydrochloride 4G
5. 3. Wettable Powders (WP): It is a powder formulation
• To be diluted with water and applied
• Yields a stable suspension with water
• Active ingredient (toxicant) ranges from 15 to 95%
• Toxicant is blended with a diluent, a surfactant and an auxiliary material
• Sometimes stickers are added to improve retention on plant surface
• Loss of chemical due to run off
• More water is required
Eg: Carbaryl 50%WP, Thiodicarb 75%
4. Emulsifiable Concentrates(EC):
• Contains the toxicant, a solvent and an emulsifying agent
• Yields an emulsion of oil-in water type, with water
• Active ingredient (toxicant) ranges from 2.5 to 100 %
• When sprayed the solvent and water evaporates quickly leaving a deposit of toxicant
• The emulsifying agents are alkaline soaps, organic amines etc.
• Eg: Endosulfan 35EC, Profenophos 50EC
6. 5. Soluble Powder or Water Soluble Powder (SP or WSP): readily soluble in water
• Surfactants improves the wetting power of the spray fluid
• Anti-caking agent is added which prevents formation of lumps in storage
• Usually contains a high concentration of toxicant Eg: Acephate 75 SP
6. Suspension Concentrate (SC):
• Active ingredient is absorbed on to a filler which is then suspended in a liquid matrix (water)
• It is not dusty and easier to disperse in water Eg: Imidacloprid 50 SC
7. Flowables (F): When an ai is insoluble, a flowable formulation is developed
• Toxicant is milled with a solid carrier and dispensed in a small quantity of water
• Prior to application it has to be diluted with water
• Flowables do not usually clog nozzles and require only moderate agitation Ex;Methoxyfenozide( Intrepid 2F)
8. Water Dispersible Granules (WDG): appears as small pellets or granules
• When the granules are mixed with spray water, they break apart and, with agitation, the active ingredient becomes
distributed throughout the spray mixture. Ex: Thiamethoxam 25 WDG
7. 9. Solutions: water insoluble but soluble in organic solvents like amyl acetate, kerosene, xylene etc.,
• Some toxicants are dissolved in organic solvents and used directly for the control of household pests. Eg. Baygon
10. Concentrated insecticide liquids: the toxicant at highly concentrated level is dissolved in non-volatile solvents
• Emulsifier is not added
• Generally applied from high altitudes in extremely fine droplets
• Never diluted with water at ultra volume rate
• There is greater residual toxicity and less loss through evaporation
• Active ingredient ranges from 80-100% Eg: Malathion, Bifenthrin,Fenitrothion.
11. Insecticide aerosels:
• Toxicant is suspended as minute particles 0.1 to 30 microns in air as fog or mist
• The toxicant is dissolved in a liquified gas and if released through a small hole
• causes the toxicant particles to float in air with rapid evaporation of the released gas Eg: Allethrin
12. Fumigants: volatile at ordinary temperature and sufficiently toxic is known as fumigant
Most fumigants are liquids held in cans or tanks
They are mixtures of two or more gases
places not easily accessible to other chemicals can be easily reached Eg; Aluminium phosphide
8. 13. Microencapsulation: consist of dry and liquid pesticide particles enclosed in tiny plastic capsules
• Mixed in water and sprayed
• The capsule slowly releases the pesticide
• Prolong the active life of the pesticide by providing timed release of the active ingredient Ex: Lambda-cyhalothrin
14. Baits: In baits, a.i is mixed with edible substance
• These are always stomach poisons
• made up of 3 components, Poison (Insecticide carbaryl), Carrier or base(Rice bran), and Attractant (Jaggery) at ratio of
1:10:1
• Poison should be strong and easily soluble
• Base is the filler like rice bran with just enough water
14. Insecticide Mixtures: Involve combinations of two or more insecticides in the right concentration into a single spray
solution
• savings in labor costs
• The use of pesticide mixtures may result in synergism or potentiation (enhanced efficacy) and the mitigation of
resistance
Ex: Chlorpyriphos16% + Alphacypermethrin 1% EC
Chlorpyriphos 50% + Cypermethrin 5% EC
9. 1. Addition of Surfactants improves the wetting power of the spray fluid, e.g. Triton X-100,
Teepol, Tween-85 and soap.
2. Deflocculators/spreaders: Materials added to a spray to lower the surface tension and
improve spread over a given area. e.g. Calcium casinate
3. Stabilisers: Chemicals added to a pesticide formulation which resist chemical degradation
over a period of time.
e.g. Isopropyl cresols for Pyrethrins, Hexamethyene tetramine for Endrin, Epichlorohydrin
for Aldrin and Toxaphene.
4. The adverse effect caused by some insecticides on plants is known as Phytotoxemia.
5. Softeners are the substances that reduce the phytotoxicity of an insecticide, e.g. Sulphur,
Zinc sulphate, lime and casein.
6. Humectants increase the time of drying of applied spray particles. They keep the surface
moist. e.g. Glycerine.
7. A toxic compound when used with another toxic compound increases the toxicity is called
Potentiation.
8. The compound enhancing the toxicity of another compound when combined with it is
called synergist. e.g. Piperonyl Butoxide (non toxic) + Pyrethroids (toxic)
Piperonyl cyclonene (non toxic) + DDT (toxic)
9. Oleic acid is a Pseudosynergist. It stabilizes the droplet size and increases toxicity of the
insecticide.
10. Pyrethroids have high synergetic ratio.
11. The compound inhibiting the toxicity of another compound when combined with it is called
antagonis.
