“…It is a double sulphate of aluminium which is very frequently used topically and internally in traditional systems of medicine including Ayurveda, where it is called Phitkari or Saurashtri, and traditional Chinese medicine, where it is called Ming fan. Previously, potash alum has been tested for its larvicidal efficacy against Anopheles stephensi (Preet and Seema 2010). The present paper highlights the use of potash alum as a potent larvicide against Aedes aegypti under laboratory conditions and its impact on the biochemical profile to assess the mode of action leading to mortality.…”

Aedes aegypti is the primary vector of dengue, yellow fever and chikungunya in India and other South East Asian countries, and novel insecticides for vector control are urgently needed. In the present investigation, efficacy of potash alum, a traditionally known double salt in Indian and Chinese medicine system, was tested against the larvae of dengue vector, A. aegypti. LC(50,) LC(90) and LC(99) values were recorded for various instar larvae where I instar larvae were found to be the most susceptible and IV instar larvae as the least susceptible one. The LC(50) values of crude and standard potash alum of various instar larvae ranged between 15.29 and 48.53 ppm and 20.50-65.10 ppm, respectively. Biochemical changes were also evidenced in IV instar A. aegypti larvae following a sublethal exposure for 24 h in the levels of various nutrient reserves and primary metabolites such as sugar, glycogen, lipids and proteins suggesting possible mode of action responsible for larval mortality. Sugar and glycogen concentrations were measured as 24.6 and 10.67 μg per five larvae in controls which were significantly (p<0.05) reduced by 32.11-93.98% and 39.26-94.47%, respectively, in larvae treated with crude alum. In controls, protein and lipid content were recorded as 210.74 and 94.71 μg per five larvae which dropped up to 26.53% and 25.5%, respectively, in larvae following treatment with crude alum. Moreover, drastic changes were also recorded for DNA content with 25.39-44.17% decrease in crude alum-treated larvae. It is evident from these results that potash alum, a fairly cheaper and readily available ecofriendly compound could be recommended as a potential chemical larvicide against dengue vector at mosquito breeding sites in the vicinity of human dwellings.

Botrytis cinerea is a necrotrophic fungus that affects many plant species requiring new methods of control. In the present investigation, efficacy of potash alum, a traditionally known double salt in Indian and Chinese medicine system, was tested against fourteen plant pathogenic fungi, inhibition mechanism and field efficacy of 5% potash alum water solution (M1) against tomato gray mold caused by B. cinerea. The inhibition spectrum tests showed that M1 had some inhibition effect against fourteen pathologic fungi by adopting mycelium growth rate method. M1 had an inhibition rate of 81.5%, 100%, 100% and 93.58% against B. clnerea, P. aphanidermatum, F. equiset and S. sclerotiorum respectively. M1 could effectively inhibit mycelial growth, spores production and germination of B. cinerea. The results preliminary showed that M1 had no effect on tomato growth. Tomato gray mold caused by B. cinerea had effectively been prevented by using M1 with field efficacy, which control effect was 78.66%. So the study lay the groundwork for further research and application.

In this work, we present our results on the use of potassium alum as an environmentally friendly insecticide. This compound has the potential to rid our homes, schools, hotels, restaurants, and ships of cockroach infestations. This compound is environmentally friendly and has no hazardous effects on plant, animal, or human ecosystems. Alum was approved for medical use a long time ago. In our laboratory, we developed a novel method using potassium alum as an environmentally friendly insecticide to kill the most common cockroach in the subtropical region, Periplaneta americana (L.). Adult and nymph-staged cockroaches were left to feed on potassium alum per individual insect after a period of food deprivation. The mortality was recorded as LT50. The younger nymphs the third and early fourth instars died within 4 d of feeding after consuming an average of 0.3 mg per individual insect. Gravid females were highly susceptible to alum toxicity and experienced a higher mortality rate, with an average of 3 mg per individual female. The oothecae of the normal untreated females were 8.1 mm long and 4.13 mm wide and weighed 94 mg. The eggs laid by the treated gravid females were underweight and exhibited a dwarfism shape, and these eggs did not hatched if the females consumed the potassium alum before laying eggs. The results revealed that the adult male and female cockroaches have to consume 1 mg and 2.7 mg, respectively, of potassium alum to kill 100% of them after 1 month of ingestion. The potassium alum had to be ingested by the cockroaches to affect mortality. The effect of potassium alum was attributed to chronic toxicity and not acute toxicity. The potential applications of this novel technique will be discussed.
