Can Buprofezin pesticides be used when they bloom?

When I remembered when I was young, in the stone dam along the fields, on the chaotic trees on the mountain, and on the low locust trees, we often saw honeycombs.
We would quietly poke the honeycombs and make the bee pupae in the nests to feed the little ones in our hands.

Is there anyone who was stinged and screamed like a pig's head in order to stab the beehive? I don't know how many beatings my parents have, and how many times I was punished to stand by my teacher
.
Now, there are very few beehives in Poli, grasshoppers, snakes and insects (a small lizard like a gecko) are also rare, especially snakes and insects have not been seen for many years, and the number of wild bees has decreased significantly
.
In the past, when the spring flowers were in bloom, the orchard buzzed and wild bees were pollinating, but now there are only flies left
.
Some people say that this is caused by the indiscriminate use of drugs, and there is indeed such a reason
.
Generally speaking, during the flowering period of crops, it is strictly forbidden to spray any insecticidal and sterilizing pesticides, especially those highly toxic pesticides that are harmful to bees.
Therefore, they are required to be used before and after the flower to prevent the use of drugs during the flowering period from affecting pollination
.
There are two types of crop flowers: wind pollination and insect pollination.
The wind-pollinated flowers are wind-pollinated flowers.
The pollen contains less water and is light in weight.
It can be dispersed with the wind when the wind blows to complete the pollination
.
If spraying or raining occurs during the flowering period, the water content of pollen will increase, and it should not drift with the wind to affect pollination
.
Insect-pollinated flowers are insect-pollinated flowers.
If spraying during the flowering period will affect the visits of bees and other flowers, it will also affect pollination
.
For the above reasons, it is generally not allowed to spray any pesticides during the flowering period of crops
.
But Buprofezin is a low-toxic insecticide, which is mainly effective against leafhoppers, planthoppers, whiteflies, scale insects, aphids, etc.
It has no direct killing power against adults, and is relatively safe against pollinators such as bees and natural enemies of pests.
Yes.
Sprayed during flowering
.
Buprofezin has low toxicity, strong contact-killing effect on insects, and also has gastric toxicity.
It mainly inhibits insect epidermis sloughing, causing difficulty in larval molting, hindering the formation of new skin, delaying development, and eventually appearing deformity and death
.
Effective 3-7 days after application, and the residual effect lasts for more than one month
.
For example, when controlling rice planthoppers and leafhopper pests, you can spray with 25% wettable powder mixed with water, usually 10 grams per bucket of water
.
Like scale insects on fruit trees, black spiny whiteflies, etc.
, you can spray 10 grams of 25% powder with a bucket of water
.
When controlling whitefly on vegetables, use the same concentration
.
Like us, there are many big cherries here, and scale insects appear on some trees.
We usually spray lithosulfur mixture to prevent them before germination
.
However, there will also be fish that slip through the net during the flowering period, or if there is no stone-sulfur mixture control before the flower, then you can spray Buzazione during the flowering period to control, otherwise you will miss the best control period, and you will increase the number of scale insects you want to eliminate.
Difficulty
.
However, buprofezin is slow after all, and it has poor control effect on adults.
It is mainly used in the hatching period of pests to show its excellent insecticidal effect, and it is generally not suitable to be used alone
.
Buprofezin is a specific insect growth regulator, which is similar to pesticides such as diflubenzuron, diflubenzuron, and fluflubenzuron.
Therefore, in order to improve the insect control effect, buprofezin will be compounded with pyrethroid pesticides, fenbucarb, and diflubenzuron.
Pesticides with fast insecticidal speed such as triazophos cannot guarantee that they can be used during the flowering period of the crop
.
Buprofezin can not be mixed with fine soil to make poisonous soil and sprayed on cabbage and radish ditch, nor can it touch the plants, and can not be sprayed on cabbage, radish and other crops, otherwise it will cause brown spots and green leaf albino.

.
To sum it up, if it is pure buprofezin and must be used during the flowering period of the crop, if it is just during the blooming period of scale insects, it will increase the difficulty of prevention and control after this time, then spray it
.
Otherwise, I still don’t recommend that you spray it during the flowering period of the crop.
Although spraying Buprofezin during the flowering period of the crop cannot directly kill the adults of pollinators such as bees, it can reduce the amount of eggs laid by the queen bee and other adults, making it impossible to lay eggs.
It dies soon after hatching or hatching, or it may die as a deformed pupa
