How to treat a pear in the spring from pests

3% Bordeaux mixture solution | Scab | 300 g for 5 l of water | In the autumn before wintering |
Copper sulfate | 50 g for 5 l of water | During the swelling of the kidneys | |
Colloidal sulfur | 50 g per 5 l | Process the pear in the spring 5 times with a break of 10 days | |
"Decis", "Topaz", "Aktara" | Ants, aphids | According to instructions | As pests appear |
"Nitrafen-300", "Karbofos-90" | Gall mite, scale insect | 300 mg of "Nitrafen" is diluted in 10 liters of water | Early in spring, while the buds are just swelling and immediately after flowering |
Other chemical preparations for saving pears from harmful insects in spring and autumn:
- "Spark double effect";
- "Nembat";
