Grape (Vitis vinifera L.) vine is grown in West and South India

especially in Maharashtra and Andhra Pradesh, to a great extent.

The varieties gowns are Anab-e- Shahi and Thomson Seedless.

The grapes are grown on different training systems depending

upon the varieties and the purpose for which they are grown.

These different systems allow the growth of various types of

weeds

Introduction

In Bower system,soon after pruning of grapes, there is lot of sunshine

underneath which allows the growth of cyperus rotundus and Oxalis

corniculata.

After sometime, the vegetative growth of grape increases and shades

the underneath space with result Polygon plebejum, Euphorbia

geniculata, Amaranthus viridis, Portiulaca oleracea, Oxalis sp. And

Mullugo pentaphylla among dicots and Digitaria marginata, Eleusine

indica, and Setaria glauca among monocots come up.

Weed control methods Control of weeds in grape is very important to maintain the yield and

quality levels as it is a commercially important crop.

The Different weed control methods are as follows

Hand weeding

Mechanical method

Mulching

Cover cropping

Chemical weed control

Hand weeding

Euphorbia geniculata and E. hirta, which appear as

major weeds, carry fungal and insect pests and act as

alternative hosts.

They use khurpi, a small hand operated implement, to remove the weeds.

The usual method of weed control in manual by employing women labour.

Mechanical method

In mechanical method of weed control by using bullock drawn

implement is very common in Maharashtra.

But in young orchards, the root system

of grape being shallow, mechanical

methods using machinery becomes

difficult.

In scientific orchard management,

motor run tractors and power trillers

are used to cultivate the inter rows of

grape.

In such cases, usage of spade

for hoeing is preferred.Previous Next End

Mulching

Mulching with inorganic materials like black polythene

film and organic materials like sarkanda, wheat and rice

straw, sugar cane trash, dried leaves and saw dust have

been advocated for conserving soil moisture and

fostering rapid growth of plants.

Sarkanda was found to be the best

mulch for grape in Punjab and black

polythene in Tamil Nadu.

Cover cropping

The general cover crops grown in grape orchards are :

French beans

Cucurbits

Sun hemp and

Mung

Cowpea

Chemical weed control

Chemical weed control using herbicides has been tried in grape

by several workers.

These worker have used either simazine, atrazine, diuron,

dalapon, oxyfluronfen, paraquat, or glyphosate.

Except paraquat and glyphosate, which were used as post-

emergent sprays, all other herbicides were used pre-emergent to

weeds.

One spray of atrazine or simazine or diuron at 2.0 kg a.i./ha as

pre-emergent spray followed after six months by two post-emergent

sprays of parquat at 2.0 kg a.i./ha at three monthly intervals for grape

cv. Banglore Blue.

Oxyflurofen at 1.0 kg a.i./ha as pre-emergence spray and glyphosate

at 3.0 kg a.i./has post-emergence spray proved very effective for

controlling weeds for four and six months respectively in grape cv.

Anab-e-Shahi.

Herbicides in mulched vineyards have also been tried successfully.
