Need Of Help ON These Pests!

z3r0_

Hi,

This is my first post on this matter. I have recently bought some Bonsais and am becoming a very big enthusiast. Today I was looking at my Bonsais and discovered that they were being atcaked by some pests.
I have a Pinus Parviflora and think that it's got aphids. Here is a picture of it:



The other Bonsai, I don't have a clue to what species it is, but it has black spots under the leaves, could you please tell me wht kind of pest this is. Here is a pic:



Can anyone help me on the best treatment to use in each one of them?

Thanks! Regards from Portugal!

You might want to start thinking of doing a monthly insecticide spray. I don't use any of them on the market, but use this:

CARL’S SOAP SOLUTION!


INGREDIENTS
Water
Dish Detergent
Rubbing Alcohol
Vegetable Oil

DIRECTIONS
Fill a gallon jug with water and add one (1) or two (2) tablespoons of dishwashing detergent and one (1) tablespoon of vegetable oil (or Neem oil). Shake up the gallon jug to mix the ingredients.

Fill this solution from the gallon bottle into a spray bottle and just before using add 1 to 2 two caps full (from the rubbing alcohol bottle) of rubbing alcohol and spray immediately. If you do not use the full bottle of spray, the next time you are going to use the soap/alcohol solution add the same amount of rubbing alcohol again, since the alcohol will evaporate. You can store this soap/oil solution in the gallon jug for months on end. It does not seem to go bad.
Spray on plants covering all leaf and stem surfaces. You may have to spray from three to four times with intervals of three days. This works for almost any kind of pest that attacks your trees, including scale.

I do not wash off the spray and have seen no adverse reaction to the trees from this mixture.

I use this mixture once a month as a preventative treatment, you might want to try it as well.

Hi,

Thanks for the tips, I will start doing that. But there is one problem... I was so concerned about the sufferment of my bonsai that I wen to the hipermarket and bought an iscesticide spray. I applied it just before I came here to see if anyone had replyed to me. It has 0,02% of Bifenthrin... I read a post were someone was saying that is very lethal to me and the Bonsai (don't worry I used gloves). So do you think I shoul stop aplying the insecticide and star with your solution every three days?

Cheers!

Any insecticide has to be specifically for that type of plant, or it can kill it (from what I know.) For safety precautions and to put your mind at ease, just use that spray once every 7 days for about a month, then just switch to doing it monthly.

isnt that fungi?
or is it insects?

G'day z3r0...

A couple of things about insecticides, pestisides and fungicides based on my experience...

Always start your pest treatment with the least toxic method...a stiff spaying with that highly technical instrument, the garden hose...then, if that doesn't correct the problem move up to Carl's...and, if that doesn't work, move on to the "chemicides".

Before you use any insecticide or pesticide or fungicide...or should I say simply any "chemicide"...on your bonsai, be certain that you have conclusively identified your subject pest/problem. Then use ONLY that "chemicide" that is identified on the label. And, follow the label directions.

There is RARELY any need to give your bonsai any preventative treatment. If you keep your bonsai clean and healthy, and keep your growing area and your display area clean, you will rarely have any need for the use of any of the "chemicides".

Furthermore, if you check each bonsai every time you water, you will most likely discover any pest or infection that hits you before it spreads beyond one or two plants.

Remember what Carl says about his Soap Splutiom "...You may have to spray from three to four times with intervals of three days. This works for almost any kind of pest that attacks your trees, including scale. I do not wash off the spray and have seen no adverse reaction to the trees from this mixture...".

I have used Carl's Soap Solution a few times...as in three or four...over the last 7-8 years. I have had NO REASON to use any of the "chemicides".

This is what works for me...it might work for you, too...or not.

So, keep it clean...or not. Check 'em often/daily...or not. Least toxic...or not.

Your bonsai. Your choice.

Your second tree is an azalea, i believe. If it is an azalea, you can pretty much bet the black dots are from an insect called "lace bug".

Hi,

thank you all so much for all the advice, and thanks for identifing my second bonsai. I have good and bad news. The good news is that the bonsai with aphids is completly healthy and growing nicely. The other bonsai has started to loose her leaves and getting ugly. I live in Portugal, in the northeast, I can't put my bonsais outside because they would die due to the extremely cold weather, so I have them inside my apartment but make sure they get as much sunlight as possible. I water them when i see it's necessary. I ask anyone who could help, the following question: Do you think the leave falling is a transition from the weather of the breeder to the weather where I live or do you think it's the pest that JayC said. In any case I am going to use Carl's soap solution.

Thanks!

Regards...
