When is the most suitable time to apply post-emergence herbicide to peanut seedlings?
During the growing period, peanuts will produce various weeds, and if these weeds are not removed in time, they are very likely to be taken over by weeds, leading to reduced peanut yield. So when is the most suitable time to apply post-emergence herbicide to peanut seedlings?
1. When is the most suitable time to apply post-emergence herbicide to peanut seedlings?
Post-emergence herbicide for peanut seedlings is generally best applied at the 2-4 leaf stage of the weeds, and it is advisable to spray before 10 a.m. and after 4 p.m. When spraying, remember to dilute twice, and do not spray when there is standing water in the field or rain or dew on the leaves.
2. What post-emergence herbicides are available for peanut seedlings?
1. Quizalofop-p-ethyl + fluoroglycofen-ethyl: the price is very cheap, but weeds tend to rebound, and it is also ineffective against purple nutsedge.
2. Quizalofop-p-ethyl + fomesafen: the price is a bit more expensive than the first one, but it is not prone to rebound, and it is likewise ineffective against purple nutsedge. What needs to be noted here is that data show that using this formula in the north is prone to causing herbicide damage, while it is relatively stable in the south.
3. Quizalofop-p-ethyl + bentazone: the price is higher than the above two, and it mainly targets purple nutsedge, but the amount should be appropriately increased. It will not leave residue, and its effect on other weeds is average.
4. Quizalofop-p-ethyl + bentazone + acifluorfen: a three-way compound. First, regarding the effect, it is certainly better than the above two-way compounds. It works well on common weeds in peanut fields as well as purple nutsedge, and it also leaves no residue. The only difficult thing to accept is the price, which can be 2-3 times more expensive than commonly used ones.
5. Quizalofop-p-ethyl + bentazone + fomesafen: it is likewise a three-way compound, and its weed control effect is also good, but compared with point 4, this formula can also be used on soybean. In other words, it is a herbicide that can be used on both peanut and soybean, and likewise, the price is not low.
