"SEC | S20W3:"Identification and Elimination of Crop Pests"

Modern technology is being used in present day agriculture. Every aspect of agriculture is being improved by technology. Pesticides are being used for diagnosis and prevention of crop diseases and are both cost and time consuming compared to the old methods. Today I have learned a lot as a third week agriculture student and am going to share some of my practical experiences.

When you visited the crop field, what pests did you notice? How did you identify that it was a worm?

^{Invasion of maggots at the beginning of seedling and at the end of paddy season}

I am directly and indirectly involved in the production of several crops. I produce some crops including rice, potato, chilli, maize. When I visit the field this time, the paddy season is on and the crop is 20+ days old at which time the rice plants are infested with maggots. The presence of maggots can be observed with the drying of rice plants. Also other pests are seen at different times. These pests are black-headed weevil, rice leaf-roll disease, brown planthopper, hopper, anthracnose, and also the farmer's enemy, the rat. Anthracnose is a fungal disease that causes root rot, while brown grasshoppers suck the sap and eat the sap. Basically, the presence of pests can be detected by regular monitoring of crops. Rats are the most damaging to rice. Rats cut the paddy plants in different parts of the paddy field and carry the crop to the pit.

Which pesticides do you think are suitable for controlling the pests you have observed in the field? Express your own opinion. (Note: For your convenience, pesticide group names are listed above.)

We try to control it with majra daman and shikar nematode. The first enemy of rice is this maggot, which causes great damage to the crop if not controlled at the right time. Let's mention some of the pesticides I use. We use several pesticides in our different fields.
I use Kartap, Flupyridinfuram + Flonicamid, Fipronil for control of maggots.

For nematode control we use granular insecticide 10g which is significantly effective in nematode control.

Azoxystrebin + Difenoconazole is used for fungal control.

I use pymetrazine + nitenpyrum for brown planthoppers.
