Clam aphid. Durian enemy.

Clam aphid. Durian enemy.

When we find an unusual durian leaf that looks like this, it looks like a bright pigment....And if we reverse under the leaf, we will see a small scale, like a tortoiseshell, filling the entire area under the leaf...This can be said to be the destruction of the clam aphid.

"Aphids" are very difficult to eliminate, no matter what kind of good medicine they use, because there will be aphids that will make a hard shell of chitin as hard as a tortoise's carapace, which is difficult to penetrate its armor.. Therefore, it should be sprayed repeatedly (do not forget to switch drugs) and hit the aphid by living under the leaf, so it must be sprayed as much as possible under the leaf.

As for the prevention and removal method, it is important that Durian gardeners regularly check the garden. If they find an aphid epidemic, they quickly remove it by cutting off the epidemic.

For a group of chemicals that can remove aphids.

- Petroleum oil, white oil

- Group 4, such as imidacloprids, thiamytoxams, acetamiprids, dinotifurans (this group is effective in recognizing aphid)

- Group 1 Pirymiphosmethyl, Diazinon, Prothiophos, Malatyon

- Group 6, abamectin.

- Group of 16 buprophecines (egg buttocks)

- Group 23, Spiromesifen, Spirotetramat (egg)

* * Effective disposal of aphid must focus on the oil group or EC formula as an ingredient. It will work best, but be careful about spraying in the flower and leaf stage. Toxic and leaf symptoms can occur.

* * Spouting other non-EC formulas should add whiteoil or petroleum oil instead of leaf binding agent will be effective.

* * Note that starch aphids and aphid epidemics should be abstained from spraying group 2, fipronil, and group 3, pyrethroids such as cypermethrin, because they will cause increased aphid epidemics. In addition, black ants, itchy ants and ant nests should be eliminated because they are carriers of starch aphids to spread throughout the plots. Group 1 and 4 substances eliminate ants well.
