Many different species of aphids are commonly found onapple trees. These insects feed on plant sap by piercing the leaves and stems with their specialized mouth parts. Aphid infestations can cause yellowing and distortion of leaves, stunted growth, and the development of sticky honeydew on fruit surfaces, which can lead to sooty mold growth and reduced marketability of the crop. Management of apple aphids typically involves monitoring populations during the growing season and applying targeted pesticide treatments when economic thresholds are exceeded, along with cultural practices such as pruning to improve air circulation and remove heavily infested shoots.

Sustainable Agriculture
Sustainable agriculture is an integrated system of plant and animal production practices having a wide range of environmental and other benefits. These practices support productive farming by meeting society's present food and textile needs, without compromising the ability of future generations to meet their own needs.
The practice involves many methodologies, including crop rotation, composting, minimal pesticide use, and conservation of water resources. These techniques help maintain soil quality and protect local ecosystems while reducing production costs.
Sustainable agriculture also emphasizes the importance of soil health, biodiversity, and resilience. By reducing reliance on synthetic inputs and fostering natural ecosystem functions, farmers can create more sustainable systems that remain viable for future generations.
The transition to sustainable agriculture requires education, investment, and policy support. Organizations worldwide are working to promote sustainable practices through certification programs, research initiatives, and financial incentives that help farmers transition to more environmentally and economically sound agricultural methods.

“I just started using it, and I’m really enjoying it so far. I especially like that you can control the vocabulary by adding words you already know. And it supports traditional chinese too, which is something apps like Toucan usually don’t offer.”

“Hey. I started using this extension more and more since yesterday and play with it to get the hang of it, I realized there is a glitch on this extension. I learn English and my own language is Persian. However, in the setting I need to swap them so the app will work properly. Technically I should set Persian as the source language and English as my target one, but in this case it won't give me the Persian translation- only English on both sides. Today after some playing around I swap them and set the target to Persian and source to English and it worked!!! I just wanted to let you know in case you want to improve your work. There is another idea I would like to share with you. As you add more and more vocabs to the list by time, the browser automatically inserts the translation of the words instead of the main language of the article. So you end up with a page full of half translated vocabs and half in target language and it looks like a mess. It would be so great if the words already added to the list only turn highlighted and you see the translations when you hover on them. The extension is already great and useful. I just wanted to share these points that occurred to me to help you improve it. Thank you”

“Simple and great. It would be nice if there is a feature that randomly select a few word on the webpage and translate it to the language that I want to learn, like the plugin toucan which doesn't support Russian”
