Please watermelon farmers in the house, I need your help!

My watermelons that has been doing very well all of a sudden started turning yellowish leaves and eventually dying off! Pls what could be the cause and possible remedy?

I've always applied insecticide/pesticide and fungicides on regular basis. I'm new to this particular crop. Pls does anyone hv a solution to this?

If you applied foliar spray ( liquid fertilizer ) in the heat of the sun, they will die.
Experts in the house will add more.

Where are you growing this crop?

I wonder why I am having difficulty in making posts.

Whether network likes it or not, I must help Op.

So I will be posting little by little.

Bear with me.

@Op:

Weather is the culprit on your farm.

Causative agent is rainfall.

How is the topography of your farm?

And what is the orientation of your ridges if any?

Rain either caused erosion or leaching to make the nutrients washed away or unavailable to your crops.

Abi you planted in waterlogged area?

A pix of your farm and crops will help me to help you.

Nevertheless,

Rabbit urine (46% N) or Urea, Npk 20:10:10 or any nitrogen rich fertlizer available can be used on the affected portions.

Do you have or observe any other symptoms apart from chlorosis?

Chlorosis is the name of the problem you are experiencing now.

Do you have browning of leaves? Or any other observable signs?

The sanitation status of your neighbours pose a great treath to your farm health o. I hope you know that.

Pest and diseases are migratory and I pray they don't find you but if your neighbour farm is unkept, hmnn.

God bless your hustle.

Sincerely,

The land is well drained.... Water doesn't log there at all.

Yes, there are activities of pests there (though very little cos I always spray pesticides at most every 10days).

Boss, the thing is that...it's not as if these crops are showing symptoms of nutrient deficiency... Cos the crops would be looking very healthy, with broad leaves. Then all of a sudden, they will start turning yellow and die off.

The other thing that worries me is this other case of the leaves shilvering....I was told its a fungi related disease. So I spray fungicide every 10days as well...yet they don't unfold (though the cases of folded leaves ain't that much shaa).

I know that the yellowing of leaves is related to nitrogen deficiency in the soil. So I've made arrangement for npk 20:10:10 to be applied to the crops this evening.

Also a local farmer I spoke with about an hr ago strongly suggests that I spray "karate" on the leaves. But the thing is, I know carract to be an insecticide, just like laraforce(whc is the one I use). So pls what's ur input to this?

Waiting earnestly for ur reply!
Thanks a bunch!

Hmnn, insects sometimes develop tolerance or resistance to some insecticides that they are used to. For instance, the chemical killed their father, uncle, cousin, they are already familiar with the smell, once they percieve it, they will runaway and reappear days later.

The disease may be caused by insect vectors. But let me see the leave, stem or whole plant before I can say which is which. You take a picture of the healthy plant and take another picture of the dying plant. You also take the picture of under the leave and close to the stems.

God bless.

Ok, I dunno how your weather is there. Watermelon doesn't need a lot of water anymore after the first stage of growth and we are in the raining season.

There are still other factors if this isn't the case like..
Inappropriate addition of the chemicals you mentioned above..
The soil type etc..
Honestly I can't go into details on everything, you should do a little research on the crop online. Google is your friend

The first and foremost thing before you plant is to test your soil.
Know the history of your soil. What and what was planted before.
Diseases don't show up until the later stage. But the history will let you know what crop was harvested and the possible diseases and pest of that crop before you plant.
With these you can now decide whether to plant or to treat the soil before planting.
I am sorry to say this but the truth is once a crop or field is infected, especially fruits and vegetables, its hard to salvage it. My trainer even told me to completely forget about it.
The one and only sure step is prevention and prevention alone.
Please stop using any pesticide or whatever.
If its some other crops, we usually recommend the use of water regularly maybe and who knows God could breath to it.
But stop all or any application.
And pray

Boss, I concor.

most importantly, pls tell us where u got ur seeds from

Yellowing watermelon leaves could be a sign of Nitrogen deficiency. You may want to give the plants more water and add nitrogen with fertilizers.

@unbeatable, d rabbit urine u mentioned, is it used directly(fresh and undulated) or it needs to go through some process . If yes how? If i am to use it dirrect (d way i got it) what ratio of usage dat is urine and water? Thanks

Research ongoing. All will be ready for media and sales within 8 weeks from now.

I have the working knowledge but I want to put it in pictures for all to see and I want to have enough on ground so that I can meet demand.

Please give me some time.

Sincerely,

OK
