I find these marks on my okra leaves.

Ácaro Amarelo da Videira is another possibility.

Could you please verify if there are any mite on the leaves? if there are no mites, it is magnesium deficiency, as mentioned by Venkat Pawar.

Thanks Venkatji Venkat Pawar. I will look up the library for the remedy

Thanks Carol Manejebem | Carol . I didn't see any mites on/ below the leaves

So, these symptoms indicating a Deficiência de magnésio . 😉

Tsr Kumar , Likely Magnesium Deficiency

Thanks sur Mahadevaiah N . Have applied compost and am searching for epsom salts. As someone told me epsom salts are rich in magnesium. I also read that groundnut oil cake is also a good source of magnesium. Kindly advise. Copying Venkat Pawar. Manejebem | Carol

Tsr Kumar , Epsom salt is magnesium sulfate.if is applied to soil it takes time.so spray is better10 GM's in 1litre of water until symptoms are disappeared

Tsr Kumar Yes Magnesium Sulphate is commonly called Epsom Salt. Yes Groundnut Oil is also a rich source of Magnesium.

Mahadevaiah N Thanks sir. Will do as advised 🙏

Thanks Venkatji Venkat Pawar. I do drench the grow bags with groundnut oil cake slurry dilution of 1:5

Great discuss Venkat Pawar. Tsr Kumar Mahadevaiah N Manejebem | Carol Magnesium is nowadays very common and essential micronutrient because most of the crop suffer from it's deficiency. There's is huge availability of magnesium sulphate heptahydrate 21% in the pesticide store and farmers are advised to use in all the crops during land preparations. Thank you for the warm discussion!!
