B. Pesticide
C. Weedicide
D. biocide

Answer 1

Malathion is an organophosphate. It is an insecticide named pesticide with particularly low human toxicity. It is being broadly used in agricultural applications. Short-term exposures to excessive levels of Malathion can have an effect on the nervous system causing a range of symptoms, such as headaches, nausea, dizziness, weakness, cramps, diarrhea, excessive sweating, blurred vision, and accelerated heart rate.

Complete explanation:
Option A: Malathion is a man-made organophosphate insecticide that is frequently used to control mosquitoes and a range of insects that attack fruits, vegetables, landscaping plants, and shrubs. Fungicides, on the other hand, are biocidal chemical substances used to eliminate parasitic fungi or their spores.
Hence, A is incorrect.
Option B: It can additionally be found in different pesticide products used indoors and on pets to manage ticks and insects, such as fleas and ants. Malathion is the lively ingredient in mosquito control products which include Fyfanon and Atrapa. No pesticide exposure is risk-free since pesticide products are intrinsically harmful. The probability of experiencing adverse health outcomes from exposure to any pesticide, which includes Malathion, relies primarily on the amount of pesticide that individual contact and the amount of time the individual is in contact with that pesticide
Hence, B is correct.
Option C: These products comprise over Malathion and are frequently applied undiluted. However, they can also be diluted with a petroleum solvent which is similar to kerosene, where the petroleum solvent will make up most of the pesticide solution. Whereas, weedicides are the chemicals which are sprayed all over the field to get rid of weeds and they also do not show any effect on crop plants.
Hence, C is incorrect.
Option D: Biocide is a powerful organo-chlorine disinfectant powder, which contains a blended detergent system to enhance wetting and penetration and so it cannot be used to control mosquitoes. And it can be only used in medium and high-risk areas in hospitals.
Hence, D is incorrect.

Hence, Option B is the correct answer.

Note:
Malathion is utilized at very low concentrations to control mosquitoes and is also used as a pesticide. It is not likely that adverse health results will show up as an end result of this use for most people, however, some people may also experience health effects. For these reasons, humans ought to consider taking steps to reduce their exposure to Malathion if it is utilized to control mosquitoes.
