buttons mar-minHerbicides can categorized in two types,Selective and Non selective. In Types of Herbicides we will focus on all aspects about it.  By spraying Herbicide you can control weeds without damaging crop. Selective herbicides can be used for crops like Soybean, Sugarcane, Onion and Maize. It can be categorized as per its specific method of work.

Photo synthesis inhibitors : Many chemical reactions occur during photosynthesis activity which helps in creating nutrition in plants. Herbicides of this category stops some of this reactions which causes the death of weeds. This type of herbicides can be used in two stages. Pre emergence and Post emergence or can be sprayed in both stages.

Active Components

Selective / Non Selective

Recommended Crops

Atrazine 50% W. P.

Selective

Sugarcane , Maize

Metribuzine 70% W. P.

Selective

Sugarcane, Potato

Diuron 80% W. P.

Selective

Sugarcane

Pigment inhibitors : In plants pigment plays important role during photosynthesis activity, it protects chlorophyll from sun rays. If this pigment gets disappeared chlorophyll also disappears and weeds get white in color, which causes the death of weeds. Herbicide in this category are as follow:

Active Components

Selective / Non Selective

Recommended Crops

Tembotrione 34.4% S.C.

Selective

Maize

Topramezone 336 S.C

Selective

Maize

Cell Membrane disruptors : All herbicides in this category are known as contagious herbicides. By affecting the cells as well as enzymes of weed this disruptors controls the weeds quickly. Herbicides in this category are as follows.

Active Components

Selective / Non Selective

Recommended Crops

Oxyfluorfen 23.5% E.C

Selective

Onion

oxadiargyl 80% W.P. .

Selective

Paddy

Plant Growth Regulator Herbicides : In this category we can see 2, 4-D Herbicide. Usually this herbicides are used in Post emergence. Especially to control broader leaf weeds. If used in wrong time and wrong proportion it can cause damage to crop also. It attacks on cells of weeds and make them weak. Due to this the weeds die faster.

Lipid Biosynthesis inhibitors : These herbicides are usually used to control weed in Dicot crops. Herbicide in this category are as follow:

Active Components

Selective / Non Selective

Recommended Crops

propaquizafop 10% E.C.

Selective

Soyabean, Blackgram
quizalofop ethyl 5% E.C.

Selective

Soyabean, Blackgram, Peanut

Amino Acid Synthesis inhibitor : This category of herbicide stops the growth of weed immediately. It has two subcategories, Category A herbicides stops the process of creating Aromatic Amino Acid. glyphosate is one of the example. ‘B’ catogry herbicides are as follow.

Active Components

Selective / Non Selective

Recommended Crops

imazethapyr 10% S.L.

Selective

Soyabean, Blackgram, Peanut
chlorimuron ethyl 25% W. P.

Selective

Soyabean, Paddy
metsulfuron methyl 20% W. P.

Selective

Wheat, Paddy
