The use Of High Pesticides Must Be Reduced
Assalamualaikum wr wb
Good Morning the audience
We know that the world of agriculture is inseparable from pesticides, it is undeniable
that the use of synthetic pesticides mainly increases crop yields, but their impact on
environmental sustainability will be damaged. So, today in a special event I will tell you to
start 3 reasons why we should reduce the use of synthetic pesticides. For starters, I will give
reasons and evidence that pesticides will cause soil and water pollution. The second reason is
that the use of pesticides will make pests resistant and kill non-target organisms. The third
reason, the use of pesticides will leave residues on foodstuffs, and at the end of my speech, I
will summarize all the discussions that I have previously delivered.
First, Use of high synthetic pesticides affected water and soil pollution. The first reason
for my statement is that organisms in the environment surface water, groundwater, and soil are
contaminated. The organisms in the water will be contaminated because of the toxins contained
in the pesticide residues that flow into the river, and pesticide residues also cause groundwater
is polluted with toxic chemicals, and overuse of synthetic pesticides has effects on the soil
organisms that are similar to human overuse of antibiotics. We can see from NCBI research
paper about results show that at least 3,331 cases distributed globally, the biodiversity of
surface water areas is at risk of damage due to insecticide contamination, next, there is evidence
USGS that at least 143 different pesticides and 21 transformation products have been found in
groundwater, including pesticides from each major chemical class. Over the past two decades,
detection has been found in groundwater in more than 43 states and move to effect from the
soil is common herbicides also interfere with this process: triclopyr inhibits soil bacteria from
converting ammonia to nitrite (Pell et al., 1998); Glyphosate reduces the growth and activity
of free-living nitrogen-fixing bacteria in the soil (Santos and Flores, 1995) and 2,4-D reduces
nitrogen fixation by bacteria that live in green bean roots. And, so we know that the use of
pesticides in the long-term effect causes environmental damage such as soil or water, so there
is a need for a transition to the use of synthetic pesticides by utilizing organisms as pest control
and as soil bioremediation.
Move to the second reason, the target organism becomes resistant and the non-target
organism dies because of using the high synthetic pesticide. Why so? As an illustration, insects
that are controlled with synthetic pesticides do not kill all pests, surely there are still a few that
survive, and those that survive appear resistant traits that can eventually be passed on to their
offspring so that they can also cause population explosions and non-target organisms that might
be able to control pests die from synthetic pesticides. I will mention the example, from Gorman
Research in 2006 that said resistance of brown planthopper to imidacloprid has been growing
in Asia and this supports reports that the efficacy of imidacloprid against WBC in the field has
decreased. And also research from Laba(2010) said Excessive use of pesticides will increase
control costs, increase the death of non-target organisms, and can reduce environmental quality
because like Organophosphate, carbamate, and synthetic pyrethroid class insecticides harm
natural enemies of leafhoppers and stem borer, namely spiders. From the evidence and research
that we know, pesticides can cause resistant pests and non-target organisms to die, so it is
necessary to replace synthetic pesticides by utilizing natural enemies or vegetable pesticides.
The third reason, High pesticide use has an impact on toxic crops, very persistent
pesticides can leave residues of pesticide residues like aldrin, chlordan sis and trans, DDT
complex, dicofol, dieldrin, endosulfan alpha and beta, endosulfan sulfate for very long and can
accumulate in vegetable and fruit tissue so that fruit and vegetables are at risk of containing
dangerous toxins if consumed by humans. We can see from a Research paper from Amilia et
al 2016 From the results of a simple statistical analysis of 100 farmer samples, it is known that
the average risk intake for farmers is 1.505 g / day with the highest value of 4.014 g / day and
the lowest risk intake is 423 g / day. From the results of these calculations, it can be seen that
the amount of vegetable and horticultural consumption by farmers as much as 1.505 g / day
contains health risks in the form of accumulation of pesticide residues that can be harmful to
health. So, we know that the high use of pesticides impacts human health through pesticide
residues in food, so it is necessary to regulate the level of toxicity and also try to replace the
use of synthetic pesticides with natural pesticides, and there needs to be preventive action
before consuming food ingredients.
In conclusion, people or if a farmer needs to reduce the use of high pesticide. It is
because will cause soil and water pollution, and next will make pests resistant and kill nontarget organisms, and also pesticides will leave residues on foodstuffs. So, I suggest reducing
the use of synthetic pesticides and slow start to use environment material.
Thank you
